Ambassador Sarek offered them the protection of Vulcan for going after Spock. As long as they stayed on Vulcan, the Federation couldn't arrest them. It wasn't made explicitly clear in the final film, but that's what happened.
There was a scene scripted in III, but not filmed IIRC (it was however in the novelization) where Uhura, after beaming Kirk and Co to the
Enterprise, went straight to the Vulcan Embassy to avoid arrest by claiming asylum.
Kirk mentioned being in a "Vulcan exile" but nothing specific that the Vulcan government was preventing Starfleet from arresting them.
That's what the concept of asylum
means, dude. One government protecting (for whatever reason) a person from the power of another government.
Has nothing to do with asylum.
Only in those matters where the Federation has jurisdiction.
So does the UN, but under different names.
So the Federation government is the highest level of authority in issues of domestic law as well.
No. Flat wrong. Proven numerous times. Domestic law is the judisdiction of local planetary authorities. This goes all the way back to "Wolf in the Fold".
Just like the how the US supreme court is the highest authority in its land. There's no court in the United Nations or NATO that can overturn its decision
Only because the full extent of the UN has never been ratified and put into action.
I know what asylum means dude. As you said, there is nothing in the film that specifically says they were there under political asylum (no wonder I don't remember it). I did not read the novels so I can't comment on that. And exile and asylum are not the same thing. Exile means you were forced out by your home government. Asylum is a foreign government protecting you from your home government. Kirk obviously didnt mean he was exiled from Earth in the literal sense
Yes Federation law applies to matters in Federation jurisdiction. Just like US federal law applies for certain crimes, state laws for others, municipal laws for traffic offenses and shit like that. So whats your point?
Yes the UN has never been ratified to be a sovereign government. That's why their court has no power in domestic America affairs, where the Federation supreme court does have final say in judicial affairs in Federation space. That is the whole point of this debate.
Now I see why this idea of the Federation being a peacekeeping organization keeps going on.
The UN is no government. NATO is no goverment. The Federation is a government that's why it cannot be either one of those organizations.
NATO is an alliance like the 22nd century alliance between SEPARATED military powers Earth, Vulcan Andor and Tellar.
The Federation is a SINGLE government with a SINGLE chain of command for ONE MILITARY organization. Its laws and supreme court have final say in legal issues in Federation space or concerning Federation citizens from any planet. That is why it is a sovereign power like the United States.
The UN has no parallel in Star Trek. There is no peacekeeping organization where every planet in the Alpha Quadrant can vote on sending neutral but armed starships to intervene between two warring parties.
Sure in your hypothetical UN where they are "put into action" and the Secretary General was President of Earth and the Security Council forced all the countries to combine their military forces into one chain of command and the international court became the final supreme court of the world, then yes the UN would be a sovereign state. But right now as it stands, the UN recognizes equal sovereignty for all member states, not the other way around.
By the way the one example you provided where I'm flat wrong, Wolf in the Fold, that wasn't a Federation planet
