Long story short, all cases start with a brief hearing of what the case is being brought to the court. This is mostly to prevent frivolous lawsuits - court time is tightly scarce. So that was your chance to lay out what the case you have consists of. The burden of proof of this point is not high, so understand that the legal standards of the case would have to be particularly weak not to make it past this point to procede into court - AND IT DID NOT. The "evidence" that has you so convinced did not meet even the most basic of legal standard - qualifications under the hearsay rule, qualifications under standing, compliance with the Federal Rules of Civil Procedure, and, oftentimes, straightup not even having the proper paperwork! Stuff that would get a lawyer fired from a reputable law firm! I really cannot emphasise enough the low calibre of legal staff that was bringing this case to the courts! - so that despite 70 lawsuits being filed, not one single vote - NOT ONE - was proven fraudulent.
So, yes, it made it to court, it just didn't make it past the most basic checkpoints of a court against frivolous lawsuits and inadmissible evidence.
And the question that I would like to pose to you is: if it's not good enough to convince a court, why is it good enough to convince you?
