So let's have this unknown person testify to the appropriate House committees. Let he or she identify the source(s) within the White House who heard the call, and conveyed impressions to that whistleblower. There are others besides the unknown whistleblower to hear from.
As for a court of law, in this instance, that would be the Senate, since we're talking impeachment. I don't want to see an obstruction of Congress count as the only Article of Impeachment. I want to hear the evidence, and hear from the witnesses and informants where the Ukraine matter is concerned. But, your president is refusing to recognize that the Constitution grants the Legislative branch the checks and balances power of oversight over the Executive branch. This is very unconstitutional of him, I believe.
We were supposed to hear from the EU ambassador, Sondland, yesterday. Earlier in this thread you made a point of stating that nobody here wanted to mention that Sondland said "no quid pro quo" in the text message exchange with Taylor. But, what you did not mention is that there was a 5 hour gap between Taylor saying it was "crazy" to link assistance to Ukraine with investigating the Bidens, and Sondland's next text reply. Further, of all the comments in the text exchange, that reply by Sondland sounds like it was written by a lawyer. You also failed to mention that Sondland ended his text by saying let's stop texting about this. I wonder why. Actually, no, I don't:

Ambassador to the European Union Gordon Sondland consulted directly with President Donald Trump before telling the top U.S. diplomat in Ukraine that there had been "no quid pro quo” regarding the administration's pressure campaign on the country and urging the diplomat to stop texting about his concerns, a person with knowledge of the call confirmed to NBC News.
Sondland spoke to Trump by phone on Sept. 9 before responding to acting Ambassador to Ukraine Bill Taylor's remark that it would be “crazy” to link Ukraine assistance to help with a political campaign, the person said. When Sondland responded several hours later,
he told Taylor that Trump had been “crystal clear” that there had been no quid pro quo.
