Por que não havia “nenhuma prova” de que Naboo estava sendo invadido?

LOTT DOD: I object! There is no proof. This is incredible. We recommend a commision be sent to Naboo to assertain the truth.

VALORUM: Overruled.

LOTT DOD: Your Honor, you cannot allow us to be condemned without reasonable observation. It's against all the rules of procedure.

A third box representing Malastare moves into the center of the room. AKS MOE, the Ambassador, addresses the convention.

AKS MOE: The Congress of Malastare concurs with the honorable delegate from the Trade Federation. A commision must be appointed...that is the law.

Observe que ninguém está dizendo que as acusações de Padme devam ser ignoradas ou esquecidas, mas que elas devem ser investigadas por uma comissão independente. Sim, tal comissão teria descoberto que a Federação do Comércio havia invadido ilegalmente - se alguma vez decolasse, com Palpatine desacelerando tudo.

Isto é o que significava anteriormente no filme quando Sidious estava falando com Gunray:

DARTH SIDIOUS: Good. I have the Senate bogged down in procedures. By the time this incident comes up for a vote, they will have no choice but to accept your control of the system.

A maioria das evidências que a Rainha tem com ela poderia ser facilmente fabricada; a única evidência independente que ela tinha era o testemunho dos Jedi, e eles não estavam lá. Se ela estivesse pensando claramente, ela provavelmente os teria chamado, mas ela não estava pensando claramente. Ela foi cuidadosamente preparada e manipulada por Palpatine:

PALPATINE: ...the Republic is not what it once was. The Senate is full of greedy, squabbling delegates who are only looking out for themselves and their home sytems. There is no interest in the common good...no civility, only politics...its disgusting. I must be frank, Your Majesty, there is little chance the Senate will act on the invasion.

AMIDALA : Chancellor Valorum seems to think there is hope.

PALPATINE : If I may say so, Your Majesty, the Chancellor has little real power...he is mired down by baseless accusations of corruption. A manufactured scandal surrounds him. The bureaucrats are in charge now.

AMIDALA : What options do we have?

PALPATINE : Our best choice would be to push for the election of a stronger Supreme Chancellor. One who will take control of the bureaucrats, enforce the laws, and give us justice. You could call for a vote of no confidence in Chancellor Valorum.

AMIDALA : He has been our strongest supporter. Is there any other way?

PALPATINE : Our only other choice would to be to submit a plea to the courts...

AMIDALA : There's no time for that. The courts take even longer to decide things than the Senate. Our people are dying, Senator...more and more each day. We must do something quickly to stop the Federation.

PALPATINE : To be realistic, Your Highness, I'd say we're going to have to accept Federation control for the time being.

AMIDALA : That is something I cannot do.

Palpatine a preparou para ver a situação exata que eles vêem - senadores brigando, nenhum interesse pelo bem público, um pedido para que ela atrase e deixe seu povo sofrer ... então ela avança com o movimento dramático de ninguém (exceto Palpatine) esperava.

EDITADO PARA ADICIONAR:

Esqueci de abordar isso quando respondi pela primeira vez, mas a descrição da missão dos Jedi da pergunta:

The personal testimony of multiple witnesses, including two Jedi (who, as the opening crawl tells us, were dispatched by the Supreme Chancellor to investigate this very issue)

... não está correto. O rastreamento de abertura diz:

While the congress of the Republic endlessly debates this alarming chain of events, the Supreme Chancellor has secretly dispatched two Jedi Knights, the guardians of peace and justice in the galaxy, to settle the conflict.....

Em primeiro lugar, isso é política. Mesmo em uma galáxia bem distante, existem fatos alternativos.

A segunda parte da sua pergunta foi abordada por Steve Sansweet, (ex) Lucasfilm Head of Content / Head of Fan Relations no antigo " Pergunte ao Conselho Jedi "no site oficial da Starwars.com.

Q. Why didn't Qui-Gon and Obi-Wan testify on the Queen's behalf during the senate hearings? They had proof of the Trade Federation invasion. They were there!

A. In the opening crawl to the The Phantom Menace, you'll note that it specifically says that "Chancellor Valorum has secretly dispatched two Jedi". There's the key word: secretly.

The Jedi didn't testify because they weren't really supposed to be there. ("The chancellor should never have brought them into this," says Sidious). Valorum, knowing full well of the Senate's inefficiencies, didn't bring the matter of sending Jedi ambassadors to a vote. So, he took it under his own authority to send the Jedi to Naboo.

Already mired in "scandal and baseless accusation," Valorum couldn't bring up the unauthorized Jedi mission for fear of political recrimination. As it turned out, Valorum was ousted from office anyway, and the Jedi were preoccupied with Qui-Gon's claims of finding the Chosen One of ancient prophecy.

_{^{Starwars.com - Ask the LucasFilm Jedi Council}}

Há no máximo três testemunhas independentes da invasão, dois Jedi (um dos quais ainda é um padawan) que podem ter sido comprados ou ter segundas intenções por sua lealdade e um Gungan de intelecto questionável que provavelmente diria o que quer que ele é dito para. Provas de vídeo podem ser facilmente fabricadas e a perda de comunicações pode ser falsificada.

Imagine o ovo nos rostos do Senado quando eles têm que explicar ao público como milhões de créditos foram desperdiçados por causa de uma disputa mesquinha em algum planeta distante. Eu, pelo menos, exigiria a renúncia imediata do representante dos meus planetas!
