This is not at all true, I recommend you look into the exact meaning of "legal standing".

Yeah, so funny, *yawn*.

Try to contribute to the conversation, though.

What you say is also untrue, there's a minimum set of requirements that have to be met regarding discovery, etc.

In the US standing is a specific legal concept about whether you have a valid reason/role to bring up a particular issue. For example most of Donald Trump’s lawsuits around the 2020 election were rejected for a lack of standing rather than on merit (whether the case is any good).
