One of the basic rules of being a party in a lawsuit is that you must have “standing”, which means a stake in the outcome more than that of an ordinary citizen. So, ordinary citizens can’t join lawsuits solely on that basis.
Ordinary?
That sounds like word games. Using that logic one could hurt all citizens with their unconstitutional and illegal behavior so as the harm becomes ordinary and the ordinary citizen looses their standing.
Nope.
All US citizens have a stake in this outcome
So a good friend of mine was one of the poll watchers in Detroit who was prevented from exercising his duty. Does he have standing?
