The Wizengamot and related bodies

[sunnyskywalker]

I've been trying to figure out how the wizarding legislative/judicial branch works, with little luck. In a way, this is actually realistic; anyone who's ever tried to sort through how the various commissions and committees and departments and offices and programs etc. of a large government are related has probably had similar moments of bafflement. But I'd still like a semi-coherent picture of the government of wizarding Britain.

We know that the Wizengamot passes laws, so they're sometimes a parliament (apparently unicameral). But they also apparently act as the highest court. Being tried by "the full Wizengamot" is a big deal.

So far, so good. But here the neat Wizarding Branches of Government for Kids version breaks down.

In OotP, Harry is tried before the full Wizengamot. There are about 50 of them, wearing purple robes with big Ws on them. In GoF, he witnesses three memories of trials and trial sentencings. Karkaroff's is a closed trial, so we can probably assume that everyone on the benches is involved in the trial somehow. There are about 200 of them, and they're not noted as wearing official Wizengamot robes (which would be noticeable). Dumbledore refers to them as "this council," and it seems to be the Council of Magical Law. Then at Bagman's trial, there's mention of "the jury" to Crouch's right, as opposed to the spectators on other sides of the room.

If the Wizengamot is the highest court, why were those three important trials tried before the Council of Magical Law? (Gosh, Harry must really rate high on the threat-meter!) And why is the Council four times bigger than the Wizengamot? How exactly are the Wizengamot and the Council of Magical Law related? Is the Council composed of the full Wizengamot (not in their W robes, since they're not acting solely as the Wizengamot) plus 150-ish other people--and who are those people? Are "the jury" at Bagman's trial the Council (crammed onto one side of the room to make room for spectators), the Wizengamot, or a jury from yet another source?

Looking at the characters whose identities we know makes things even more puzzling. In the 1980s trials, the DMLE head (Crouch) acts as judge and chief prosecutor. At Harry's trial, the Minister for Magic (Fudge) takes on that role. Maybe the Minister is the official highest prosecutor-judge, but may delegate the job to the DMLE head? Or maybe the Minister is the prosecutor-judge for the Wizengamot, but the DMLE head holds that role for the Council?

And the presence of both of those officials means there isn't a sharp division between the legislative/judicial and the executive branches. This impression is reinforced by the initial trial plan for Harry, in which the DMLE head (Bones) was going to hear his case privately in her office. Are most trials handled by DMLE officials? Are medium-sized trials handled by a small panel of DMLE and/or Wizengamot and/or Council members? (Like, there's the Murder Panel, the Arson Panel, the Apparating Without A License Panel...) Oh, and we also hear that the Muggle Protection Act is "Arthur's law," even though he's an office head and not on the Wizengamot. Did he write it and get a Wizengamot member to propose it for him? Can department and office heads propose legislation directly?

Also, we see that DMLE head Amelia Bones is a member of the Wizengamot. She and Senior Undersecretary Dolores Umbridge sit next to Fudge and help question Harry. Are all high Ministry officials--department heads, the senior undersecretary, and the Minister--automatically granted seats on the Wizengamot, or did they acquire the positions separately? How many government positions can you hold concurrently?

In the 1980s trials, Dumbledore and Moody are sitting next to Crouch on the highest bench, but not asking any questions. Are they supposed to be his backups for interrogating the defendants? If so, why are they acting as the peanut gallery instead of doing their job? If the Chief Warlock of the Wizengamot is one of the people eligible for that role (only for the Council, or for Wizengamot trials as well?), maybe Dumbledore wouldn't have been on the bench in OotP even if he were still Chief Warlock because he was acting as Harry's barrister instead (which evidently they don't normally have). And Moody had retired by OotP, so he wouldn't be there as the Auror Office's representative. (Was there another Auror there, like Scrimgeor, and Harry just didn't notice? Do they only get a representative on the Council of Magical Law, but not Wizengamot trials?) I don't think Moody was ever confirmed as the head of the Office, so either that person delegated the job to Moody, or they can pick who gets to be Auror representative. Or maybe Dumbledore and Moody are just so important that they can demand to watch any trials they want from the best seat?

Also, there's always the possibility of procedural changes between 1982 and 1995, just to make things more complicated.

Given that the DMLE head seems to be a hair's breadth from being literally the wizarding world's judge, jury, and executioner, it's no wonder we got a would-be despot like Crouch. The power structure positively encourages it. I mean, the guy was effectively the Chief Justice and the Commander in Chief! At the same time! And maybe had legislative powers too! How do they expect that to work out?

And we also never hear anyone comment that there should have been any legal impediment to Crouch trying and sentencing his own son. They really don't have any sense of conflict of interest, do they?

Anyway. The Wizengamot, the Council of Magical Law, and the executive departments: does anyone have ideas on how to sort out this tangle?

Comments

[chantaldormand]

I think that about 2/3 of your confusion about the Ministry comes from your approach; you take handful of cases that have extraordinary circumstances and take them as a baseline for your analysis. If you want to analyse system you need to take a more broad view on things. Normally if I wanted to do something like this I would look for law books or missions statements and then compare them with how the system actually works.
But thanks to Jo's lack of education in social sciences and Harry's limited POV we need to improvise.
Let's start with this: What is MOM's mission? What is the main goal of the government? How they can attain it and what implications steams out of it? Let's compare it to similar bodies/governments that existed during MOM's creation.

[sunnyskywalker]

Well, unfortunately, we don't have much solid information, and whatever hypotheses we come up with have to allow the examples we see to fit somewhere. Arthur says Harry's trial is unusual, not that it's procedurally incorrect, for instance, so however the government is structured, it must allow for the Minister to preside over the Wizengamot to prosecute a teenager for performing magic in a Muggle area and for the DMLE head to try him one-on-one in her office.

According to Hagrid, the Ministry "mostly" spends their time keeping magic secret from Muggles. This is Hagrid, so we should allow for some exaggeration. We also know that Arthur's office--which you would think would be important under that mission statement--is staffed by only two people and treated as a joke. They also have offices for internal wizarding-world things, like the Floo network and the Department of Mysteries. So it's hard to say exactly how much they focus on hiding magic vs. other governmental tasks. A very important task being simply to keep existing, if parallels to real governments help. I can see one goal being "employ witches and wizards who might otherwise not have jobs in our screwy closed economy," which might explain the Ministry's size, but not necessarily its organization.

According to Pottermore, the Ministry was founded in 1707, and was derived from the earlier Wizards' Council, which may or may not have also been called the Wizengamot. If not, then there was a Wizards' Council and a Wizengamot simultaneously for some time, and we're not sure what distinguished them. It looks like they kept the Wizengamot in some fashion and spun off some of their authority into the Ministry departments in 1707. Maybe.

I'm not sure how helpful looking at Muggle governments would be. I'm pretty sure that random mid-level employees in the British Ministry of Defense, for example, can't waltz into Parliament and propose legislation, and that this isn't a new development. Parliament has been bicameral since the 14th century or so. Evidently they could act as the highest court of appeal until recently--but none of the trials that we see are appeals, as far as we know. Harry's wasn't. The Privy Council was not several times larger than Parliament, nor was the Star Chamber, as I recall. (Though the Star Chamber looks like it has some potential here.) We don't know of any ecclesiastical authorities in the Wizengamot, unlike Parliament. I don't know how close a parallel you can find, really. Maybe someone more familiar with the ins and outs of English political history over the last thousand years can help?

You might be able to make something fit by picking the way bits of English government worked in different time periods and sticking them together, but that doesn't help us guess which bits to pick. And then grafting that to a modern Ministry setup with departments, divisions, and offices which send out memos makes you think you should be looking later in history, not earlier.

[chantaldormand]

"Unusual trial" might mean that a minor's case being treated like that is not normal, but then again Harry is a celebrity. If your local Justin Beiber is going around breaking law "just because" (let's be honest, during peace time probability of Dementor attack in muggle town is next to none) then you have to deal with him quickly otherwise you end up with copycats.

Arthur's office deals only with enchanted muggle objects. Other than his office we have Aurors who deal with idiots who curse muggles, Creature Control office who deals with potentially rampaging creatures and Oblivation teams who erase memories. And those are only departments I can name of top of my head so there are potentially more.
Heck Arthur's house potentially falls under some department other than his.
Not to mention that Cornelius Fudge apparently started out as an Oblivator, so this is very much viable career patch :P

I asked about governments contemporary to MOM for a very simple reason: governments like to borrow solutions tested by other governments. Not to mention that WW is very backwards. So taking a look on British gov and it's neighbours might give us some kind of clue.
Not to mention that Jo is British and as such she probably used past and present British gov to create MOM :P

[sunnyskywalker]

There's still a difference between "unusual" and "outside normal rules entirely." Harry's seems to be unusual in getting bumped up to the highest level for a first offense, but no one protests "but they never try cases like this before the full Wizengamot!" So, their laws and procedures allow that possibility. And the possibility of the head of an executive department handling it one-on-one. And possibly other options in between. That's what I mean by the structure having to accommodate these cases--they're uncommon but still within the rules. So what are those rules?

Enchanted Muggle artifacts can and do cause a lot of trouble (just imagine how many people could have seen Sirius flying around on his motorcycle back in the day), so why just two people? Do they only have two people rounding up magical creatures? Only two Obliviators? If they staffed Arthur's office better, they probably wouldn't need as many Obliviators in the first place, because they'd retrieve the enchanted items before so many people encountered them! Which would better fulfill a "keep magic secret" mission. But they are oddly cavalier about their supposed main reason for existence. See also: keeping multiple Muggle campground owners around and Obliviating them ten times a day instead of arranging holidays for them while new "temporary assistant managers" run things for them.

I agree that the Ministry probably draws from British precedents, but the question is which ones. The British government has changed a lot over the centuries. And given how the rest of the wizarding world draws from different Muggle periods simultaneously (actual torches on the walls, but also a modern school calendar), the government probably does as well. So which bits did they pick, and how did they fit them together?

[chantaldormand]

Well yeah, enchanted muggle objects could cause a lot of problems, but how many wizards do something like enchanting motorbike to fly? Majority of Arthur's job are mean spirited people who do small stuff like shrinking keys. In other words stuff that can be explained away via non-magical means. "Darn I lost my keys again!" "Those stupid teenagers are exploding toilets again?".

There is also other answer to this problem: Arthur accidentally undermines his own job.
MOM seems to pay his department in peanuts so Arthur is encouraged to take bribes. For what he takes bribes? Well for cleaning the mess aka writing incident report in such way that nobody could point fingers at his patron. Probably by making it seem as it was non-magical accident that looked like it involved magic. Those silly muggles!
So if Arthur keeps viable incident reports down, MOM thinks that Arthur's dep. do not need so much funding...
It's a vicious circle.

Now, I know that we cannot depend on how historically British government was shaped. Especially since Jo's understanding of politics is very flawed.

[sunnyskywalker]

More on the government over time:

England had a Treasury (Department) centuries before the Statute of Secrecy, and a Chancellor of the Exchequer to manage a lot of the financial stuff, like taxation. But it looks like it wasn't until after the SoS that the Lord High Treasurer was established as de facto Prime Minister, and longer for that to be more official. Also, the Ministry for Magic wasn't created until 1707.

So, if they intended to be a separate or mostly-separate magical government from the beginning, you'd expect there to be a Treasury and a Magical Chancellor of the Exchequer. And the goblins were rebelling in the 17th century, so I doubt they would have given those functions to the goblins. It would make sense for the position to develop into the Minister for Magic in the new Ministry (roughly parallel to the Muggle version), because the money guy distributing funds to the secrecy-enforcing departments is effectively in charge of a big part of one of their major government concerns. But then we'd expect to hear people complain about Fudge's budget allocating all the money to the Department of International Magical Cooperation and shorting the DMLE or vice versa, even if we didn't hear his other title. But no one ever talks about Fudge's budget.

If they didn't intend to be quite so separate (like, they planned that the real Treasury would fund them, so they didn't need to duplicate it), they've most likely become separated enough since then that they need to replicate some financial handling functions in the MoM now. If this developed after they'd started using very bland, modern department structure names, it could well have gotten stuck as a subordinate office somewhere unexpected with a name much less noticeable than "Treasury" or "Exchequer." (We know they are influenced by Muggle developments, because they use the Muggle school calendar. And their departmental organization sounds very modern--no fancy, memorable titles like Lord High Beatdown-Giver or whatever.) Maybe just the Minister's Office of Budget and Finance, though that would take us back to asking why no one complains about Fudge's budget. Idk, maybe the Department of Mysteries handles it. That would make as much sense as anything.

Anyway, we can't guess which way it turned out (could be another version entirely) based on what we know. Though if they have a Treasury, it's probably in a different building, or you need to take a special elevator to get there. But this shows how hard it is to guess which eras they draw from in their government generally, and in what combination. There are precedents, but there's no exact match to one single era. Is the DMLE head a rough equivalent to the Lord High Chancellor, e.g.? If so, from which century? And they have weird factors like instantaneous transportation which probably make their setup deviate even further from their Muggle counterparts.

So it's not so much about trying to find "a" parallel as trying to find several and see if they can mesh and also reasonably fit what we see.

[chantaldormand]

//But no one ever talks about Fudge's budget.//

I wonder, in this setting does Fudge have any control over budget? Sure he seems to send Dementors and Dolores to Hogwarts, but perhaps he does it via convincing Wizengamont?

/Idk, maybe the Department of Mysteries handles it. That would make as much sense as anything./

Considering how Jo is mystified by numbers I wouldn't be surprised :D

[sunnyskywalker]

Also weird: no one ever, and I mean ever, mentions taxes. None of the rich purebloods complain about not inheriting as much as they wanted because of death duties. Fred's death duties don't imperil the joke shop's finances. No one accuses Lucius Malfoy or anyone else of hiding money in offshore accounts to avoid taxes. The Quibbler doesn't say Fudge and/or the goblins are involved in shady tax dealings. This is weird. If there are taxes, there are people loudly complaining about taxes, and we never saw a single one. Heck, in the Muggle world, trying to tax whiskey caused at least one armed rebellion!

I can explain that away by saying the wizarding world doesn't have any taxes because they fund their operations entirely by mooching off Muggle sources: embezzling money from the Muggle government, investing in the stock market, renting their vast number of real estate holdings to Muggles...

But even with an explanation, that causes a significant divergence from Muggle governments, making parallels less useful. As I recall, there were at least a few centuries when Parliament mainly gathered whenever the king needed them to get him more money somehow. Modern governments also spend a lot of time on taxes and other fiscal matters. Not having that to argue about would change things, and I'm not sure I can predict all the ramifications.

Also, even with no taxes, they also don't seem to have any governmental agency dedicated to finance, which is downright bizarre. No Treasury Department? No Department of Finance? No Controller of Currency? What do they do, just get the money, hand it out to departments based on handshake agreements, and let them spend it however? Really? No, I can't buy it. Do they keep the money-related bodies in a building other than the Ministry, so Harry didn't hear them on the elevator's departmental roll call?

Even so, you'd think government spending would come up. Allegations that not all the money allocated to the Quidditch World Cup really went where it was supposed to, for instance. Complaints that look, Quidditch is great, but the Department of Magical Sports is sucking up the entire budget for 1993/94, plus a lot of employees, and the rest of them still have work to do! Rita could have claimed Dumbledore was doing something shady with the Hogwarts accounts--and she might have been correct for all we know.

The more you look at it, the weirder it gets. Real people can't shut up about how the government is handling money. Are wizards a different species after all?

Not having a standing army was the historical norm until recent centuries, which fits with their keeping some pre-Secrecy traditions which the Muggle world has abandoned--but adopting others. They differ from many historical Muggle governments in having a (national) standing police force, which also acted as the military if you count their "wars" as actual civil wars rather than organized crime conflicts or something like that. We don't know if they have a way of calling up an army if they go to war with wizarding France.

[chantaldormand]

Let's take a step back.

The tax thing? Governments have many ways of taxing it's citizens. You can tax earnings, donations, goods, services, import etc. Considering how isolated the WW in Britain is, I wouldn't be surprised if they place a high import tax to protect local business. In fact it would fit with XVIII/XIX economic philosophy.
Then again we are reading books from Harry's perspective AKA guy who until POA didn't know that magical police=Aurors so it's hard to talk about taxes :P

Finances Dep. might be rolled into another one, heck Undersecretary's job might be overseeing employees who deal with finances.
The thing is you cannot assume things just by hearing the name of department. For example in my current place of employment out H&S dep. not only deals with health and safety hazards, but also negotiates medical contracts (in my country you have to have your health checked before you start working and it's paid by your employer) and deals with invoices concerning medical examination. That is not normal.

Heck considering that apparently wizards let goblins create their coin, in fact goblins might run finances. After all Harry never listens to HoM lectures and Bins seems to be really fond of goblins.

The complains about public spending? Again that depends on how law is written. Spendings might be published like in US; you in theory know how much US spends on military, but good luck on getting in-depth knowledge how much the military spend on each project. If this was my country I would protest, but from XVIII/XIX century perspective? Yeah, you won't find much of riots.

As for police, we are dealing with armed society. Even an eleven year old child could kill so I allow a leeway here.

[sunnyskywalker]

Harry never runs into the problem of having withdrawn X amount for school supplies and ice cream based on the prices and then finding out his ice cream budget has to go toward sales taxes. They might be only taxing alcoholic drinks stronger than butterbeer or other things he never buys, but it doesn't seem like most things have a sales tax as a matter of course. Steep import taxes are a possibility, but how much do they import? They must import some cauldrons or Percy woudln't be writing reports about cauldron-bottom regulations, but we don't know how much overall, so we can't guess how much revenue that would bring in. (Incidentally, if import taxes are very steep and yet it's still profitable to import foreign cauldrons, no wonder Percy is investigating shoddy manufacturing standards. They must be making them awfully thin to cut costs.)

Payroll taxes are also possible, since Harry never draws a salary and wouldn't know... but then I would expect to hear a Weasley or two complain about how Arthur's salary would support them so much more comfortably if only taxes weren't so high. Or someone, somewhere would. Because when the money is coming directly out of your paycheck, real people talk about that a lot. Same with inheritance taxes--the Malfoys ought to be whining about that day and night if they lost a big chunk of cash when Abraxas died, and Sirius might have had trouble affording that Firebolt after the estate paid for the deaths of Orion, Walburga, and Arcturus.

I think leeching off the Muggle world in some way is probably the main revenue source, based only on the fact that wizards generally leech off the Muggle world for so many other things (campgrounds, Muggle-built townhouses in London, trains and train stations...) But at least some of it may be more or less legitimate, if they are renting out real estate they've acquired over the centuries or something like that. And that would definitely make it more likely that wizards wouldn't spend half their time complaining about taxes, legislating about taxes, and the rest.

Oh, and I suspect there was plenty of complaining about taxes in the 18th and 19th centuries. It's just that a lot of it wasn't written down. Plus, it was harder to access information in general, but the wizarding world has had instantaneous communication for ages and would have different expectations based on that.

[oryx_leucoryx]

FYI, in some countries that are not the USA, taxes on items you purchase are included in the price, so you have no idea what proportion of what you pay is the tax.

[chantaldormand]

As Oryx mentioned tax policies in US are not norm worldwide. In fact in EU in most shops you won't find pre-tax price visible next to the product. In case there is visible pre-tax price, it's put next to post-tax price. This is because usually taxation is the same in the whole country

They at least have to import potion ingredients: as far as we can tell, there is no dragon farm/sanctuary, yet there is no shortage of dragon parts in Diagonal Alley.

IMHO Percy's job might be similar to what EU officials do. I do remember that a few years ago that to counter mass import of bananas from Africa they made regulation on how bend bananas must be to be sold in EU.
So yeah cauldron craftsmanship might be shoddy or local British guild was making fuss :P

Well inherence taxes are problems if you don't know where to look for loop holes. I like to imagine that Lucius pays quite well whoever advices him on legal and financial matters. Arthur on the other hand, could have got a decent dowry from Molly's family, but we have seem how well they manage their finances, so I wouldn't be surprised if he was slapped silly by taxes.
And Harry only hangs out with Weasleys and Hermione- people who suck at finances and girl who is supported by her upper-middle class parents.

As for Sirius? In all honesty his accounts should be frozen since he is a criminal on run, so I think he at least had to bribe goblins so he could access his account.

[sunnyskywalker]

Given how Sirius handles his bank account in PoA, I think we'd have to add an extra step: he had Crookshanks bribe the goblins for him. It's no wonder everyone thought that cat had to be an Animagus. He steals passwords, places orders through owl post, bribes goblins... is he the current Hogwarts accountant? He's probably more qualified than just about anyone else in the wizarding world!

I've heard Brits complain about VAT (value-added tax). Mainly shopkeepers and pub owners rather than customers, but the wizarding world is so small that if they were complaining about magic VAT, everyone would know about it. Maybe even the Weasleys want to think they're "above" the tawdry business of trade? Hm, that actually might work, at least halfway.

Some kind of tax must be relevant to Percy's troublesome imported cauldrons somehow, I think, even if as a proposed solution rather than the original problem. "Shoddy imported cauldrons? Well, the guild has been saying these knock-offs are killing their business anyway--we can make them happy, protect British wizarding jobs, and protect the public! Yay, us!" That's probably how Percy concludes his report, only with more polysyllabic words and passive voice.

[chantaldormand]

Now I want Crookshanks as protagonist. Even if he sleeps 18 hours per day he still would be more interesting main character :P
IMHO from my experience poor people do not talk about money, especially with children around. Heck my family is middle-class and my parents didn’t like discussing finances with us. They only started talking about taxes and economy once I was near getting my bachelors degree, so Arthur and especially Molly not talking around kids about money? Believable.

[sunnyskywalker]

Hm, interesting. My experience has been different. I mean, not talking about exactly how much money the family doesn't have at the moment, yes. That would be too shameful, and pretending even to the kids that you're not poor (just prudent or some other code word) sounds familiar. But complaining about the high price of X or the government's fiscal policy in general? Trading tips on saving and/or making more money? Making sure the kids dress "properly" (i.e., don't look poor) and telling them which careers they think offer the most stable paychecks? How to plan so that you might actually be able to retire someday? All that and more, openly. My relatives from poor backgrounds were only half-joking when they said that the first time, people foolishly marry for love, but the second time, they should wise up and marry for money.

Crookshanks probably has so many interesting adventures when no one's looking. He's definitely cleverer than half the human characters at least. Crookshanks for Dark Lord! Or Headmaster! Minister! He could do literally any of those jobs better than the humans with those titles.

[chantaldormand]

Ok, after catching some sleep I decided on how we can approach this subject.
So what is our question? "How WW government works?" Then we need to start with defining what is the MOM.
The main problem in that case is this: is British WW independent from muggle government or part of bigger public structure. How Prime Minister's politics impact wizarding population?

Scenario A: MOM is completely independent from British goverment. In this case MOM needs to create their own systems/laws/infrastructure etc. In this case your confusion would be valid: we don't see nearly enough of "meat" to support this mess. Taxation isn't directly mentioned, we don't hear about absurd law being passed, wizards munching off muggles when it comes to infrastructures...

Scenario B: The MOM and Muggle government are interconnected. The minister reporting news from WW to Prime Minister is not just courtesy on his part, but to help him build strategy around the hidden society, without revealing them.

Scenario C: MOM is part of Muggle government. In this case MOM only deals with what falls under their jurisdiction. Taxes? If they are not directly connected to magic, then it's not their problem. Law enforcement/army? Again, unless it's rampaging dragon or necromancer raising undead army for shit and giggles then it's not their problem.
This means that Joe the wizard is subject to all laws and regulations passed by both Muggle government and MOM. He should politely pay his land taxes towards the British Crown and not enchant rubber duckies to bite muggles.

But surely, the Scenario C cannot be true. Wizards are notorious in their lack of knowledge of how muggles live and often are shown to break muggle laws!
Well it's not that simple. This is where the mission statement or something similar would help. What is the main goal of MOM: maintaining secrecy OR governing population? I would say that is the former for very simple reason: half of events we see in the books wouldn't take place otherwise.
A headmaster of boarding school creating a vigilante group to fight with terrorists?
A basilisk terrorising the said school for months before it was killed by local Justin Beiber?
A supposedly dead terrorist pretending to be ex-LEO and teaching at school for a year?
Those things cannot be explained just by incompetence, corruption and Albus trying to play 4D chess.
The worst part is that thanks to WW being a secret society they can get away with all this shit. How can British government force Joe the wizard to pay his god damn land taxes if he was born at St. Mungo and was never registered in muggle institution. Heck British Crown doesn't know they could tax Joe, because they don't know that Joe exists. And the Ministry is not going tell British Crown that Joe exists, because it's not their job!

[sunnyskywalker]

I'd say Scenario B can't be true if you mean that the Muggle Prime Minister is able to do anything but say, "Thanks for letting me know about the dragons. Uh, should I clear a flight path or something?" And maybe send the MoM money under some innocuous budget line item. The visits we saw were barely even courtesies, and it seems like those were some the only or maybe only contacts the PM had with the wizarding world. So I doubt there's any kind of strategizing.

And apparently the British MoM can somehow "arrange" for the president of another country not to call; I would hope that means asking their magical counterparts to ask that president to reschedule, but given how wizards usually operate, I doubt it.

Anyway, that leaves us with an MoM which might or might not have some tenuous connections to the Muggle government, but in practice operates independently most of the time. They can deal with little things ad hoc more easily than a Muggle government due to their small size, but they obviously still have a large and organized governmental structure. Larger than you would expect, really, which is one reason I think part of their mission statement is providing employment.

[chantaldormand]

There is always a difference between how system looks on the paper and how it works in the reality. In that comment I focused how in the theory system could work considering what we know about MOM.
In Scenario B MOM would be partially financed by muggle gov. That being said there is another problem with that scenario: for muggle government to initially agree to this structure, there would have to be some kind of gain for them and more people would need to know about WW.
So how in this setting MOM would deal with muggle demands? Simple: appease them by banning some more spectacular branches of magic (which would explain why JKR's magic feels so lacklustre) and waiting a few generations before MOM starts to break the agreement. After all in post-epilogue Ron can without any consequences brainwash examiner during his drivers exam and as you mentioned British MOM can make sure that there would be no talks between British Prime Minister and head of foreign country.

Another interesting issue with Scenarios A and B is citizenship.
Under Scenario A magicals do not have British citizenship and under Scenario B they have dual citizenship, but WW's probably takes precedence.

Anyway back to the subject; the main problem that muddles up our attempts at probing MOM is widespread corruption. Characters in these books don't even try to hide that they use less than legal means to get what they want from MOM. Kind of reminds me of some texts from parts of Poland occupied by Russia during XIX century; everybody knew what kind of bribe to bring to whom.

[chantaldormand]

Now, once we figure out Muggle-Magical govs. relations and define what is MOM's job we can try take a closer look at how systems are supposed to work and how they work in reality.
On what do you want to focus? You were confused by legislative-judicial branches split? Alright let's tackle it.
The trias politica model is relatively new. It isn't until end of XVII century (John Locke) and early XVIII century (Montesquieu) that we can talk about anything resembling serious discussion about it. Somehow I doubt that wizards would lower themselves to reading Two Treaties of Government so they most probably used contemporary governments as a basis for their own :)
And here our discussion on Muggle-Magical govs. relations and mission statements comes into play. Depending on answers MOM might take completely different shape.

If the secrecy is the most important matter for MOM, then it might explain why DEs were treated in such way: they are terrorists who threaten Statue of Secrecy, they are threat to WW's way of life! But they are also fellow full-grown citizens of British WW and thus deserve right to defend themselves! Before the most important people in the country that is.
It's a bit like Congress hearing, but in this case senator might send you to prison :P
I imagine that normally if Joe the wizard cursed his collection of rubber duckies, he would be slapped with fine and there wouldn't be any trial. Well unless he tried to push back and claim he was innocent, but why do so if you can just give Arthur tickets for a sport event :P

And here we walk into another trap: no matter how we look at the MOM it's obvious that there is a lot of corruption here. Albus collecting titles like competition trophies, Arthur getting goods for covering up messes, Crouch Sr. presiding over his son's trial... there is so much wrong here that I wouldn't even know where to start mopping up this mess.
The thing is: people aren't rioting against this cesspool, because they know that if they want to, let's say quickly get a license for breeding Kneazles, all you need to do is swing by Jenny's office with box of expensive chocolates and tickets for Weird Sisters concert.

So if I had to guess I would say that there is no dedicated judicial branch. Normally it's up to DMLE to decide what to do with you, unless you push back. Then the Council is called up: all of them are members of Wizengamont who either by seniority or by greasing up palms ended up joining the body. The head of DMLE presents the case and makes sure that the Council doesn't end up sidetracked. It's up to the Council to decide what to do with your case. In special cases like Harry's whole Wizengamont is called. Why? For 2 reasons; first of all he was political opponent to Fudge, so Minister tried to escalate his case. Second reason is less obvious: Harry is magical Justin Beiber. The whole universe literally centres around him. Heck a few years earlier Minister of Magic himself waved away consequence of his lawbreaking habit and informed him in person. So we have magical celebrity who despite many warnings continues to break the law without any reason (levitating a dessert, turning family member into balloon, performing Patronus charm in muggle area). The government needs to cut end to this or citizens might start ignoring laws. After all Joe the wizard who cursed his rubber duckies collection for the third time this year will have less influence than Harry :P

As for why I say that person needs to push back to get trial? Well remember Sirius' case? I don't remember details, but to me it seems that he was send straight to prison, without any stops at Ministry. Considering how catatonic he was, I wouldn't be surprised if that was enough for the DMLE.

Mind you Sunny, political systems are not my speciality. I would need to hit books to do something more serious ;)

No, I'm fine with the legislative and judicial branches being combined (there could be all sorts of support staff to the Wizengamot who normally handle low-level cases working alongside the other support staff who do the gruntwork drafting legislation, no problem). It's the relationship to the executive departments that's unclear, because those functions seem partly but not entirely separated. I'm trying to figure out exactly how they connect.

Why is the Muggle Protection Act Arthur's law? He isn't on the Wizengamot to be proposing legislation. Is it more along the lines of what we Muggles would call a regulation?

What makes a case Wizengamot-worth (part or whole), and what keeps it in the DMLE? Is it that the DMLE normally evaluates cases to see if the case looks in any way doubtful, and if not, they enforce the fine/jail sentence/whatever that's on the books? (Unless they get a good bribe, of course.) And if the person's guilt or innocence seems in question, or it's a high-profile case, kick it up to a Wizengamot committee or all the way to the full Wizengamot? Do some kinds of crimes go before a DMLE panel and others before a Wizengamot support staff panel not because of severity or anything straightforward, but because of historical quirks like the ones that put medical contracts under the same agency as health and safety?

Also, we know the Wizengamot and the Council of Magical Law are distinct, though probably overlapping, bodies. Why is the Council so much bigger than the Wizengamot? If it were a subset of the Wizengamot plus a few other people from various departments, it ought to have under 50 members, and if it's the full Wizengamot plus some other people, still probably no more than 100. But it's around 200 people. Accounting for Harry's poor ability to estimate numbers, maybe 150. Is the Wizengamot normally the highest court, but in national security emergencies they call up the Council, which includes the Wizengamot plus... er... lots of DMLE employees and maybe other departments? That might explain why Ludo Bagman only has "a jury"--he's seen as small fry. But then, who is that "jury," since they aren't wearing Wizengamot robes? A panel drawn from various departments and/or Wizengamot support staff? And is the Minister or DMLE head normally the judge/prosecutor of one or the other, or do they have options, or what?

People totally riot about government excess and corruption in all eras. Usually they get slaughtered, but sometimes you get the Magna Carta. Maybe the problem here is that Harry mainly hangs out with Ministry-associated families, who benefit from the corruption. There could be a(nother) populist revolt waiting to happen just out of view. You could look at the war we see as partly the two factions duking it out over which one gets those sweet backroom deals.
