How does Trump win in court? (He can't.)
1. The filings of the legal actions are premature as not all the votes have been counted. Biden's team will make a motion to dismiss and these defensive actions will likely be granted. Even an appeal will endorse classic legal principles that it's too early to decide.
2. A vacuum of evidence. The Trump Team has to show a court that it has noncontroversial proof of fraud. Documents. Testimonies. It doesn't possess any such paper(s). Biden's team will make a motion to dismiss, it will be granted (not subject to success at appeal), and Trump has another temper tantrum.
3. Just making a naked claim gets you nowhere in any court in this country.
4. Trump's Team risks being sanctioned for filing frivolous lawsuits. With that loss, Trump & Team risks treble damages (the amount of damages multiplied by three and paying Biden's attorneys for their work and expenses).
frivolous
adj. referring to a legal move in a lawsuit clearly intended merely to harass, delay or embarrass the opposition. Frivolous acts can include filing the lawsuit itself, a baseless motion for a legal ruling, an answer of a defendant to a complaint which does not deny, contest, prove or controvert anything, or an appeal which contains not a single arguable basis (by any stretch of the imagination) for the appeal. A frivolous lawsuit, motion or appeal can result in a successful claim by the other party for payment by the frivolous suer of their attorneys' fees for defending the case. Judges are reluctant to find an action frivolous, based on the desire not to discourage people from using the courts to resolve disputes.
