Illegal immigrants Suing?

According the the Associated Press 7 day laborers, some of them illegal immigrants are suing Mamaroneck NY for prohibiting the use of a park as a worker pickup site. Although this lawsuit was not filed by the ACLU it certainly has their stench attached to it.

The article states "They [the day laborers] seek an injunction against what they describe as official harassment that violates their rights to free speech, free association and equal protection. The workers, all using the name John Doe in the lawsuit, claim the village "has embarked on a deliberate and coordinated campaign to harass plaintiffs and other Latino day laborers to deter them from soliciting work in the village."

As far as I am concerned, the only rights any illegal immigrant has it the right to go back to their home country and re-enter the US legally! They certainly should not have the right to file a lawsuit against a town, in which taxpayers will now have to pay for the towns legal defense, aside from the costs associated with any trial held in a public court i.e. the Judge, Clerks, Court Reporters etc.

And since when can a plaintiff enter a courtroom under an assumed name? 7 John Doe's are suing a town. I wonder if the Judge decides to rule in favor of the Plaintiffs in this case, if we will also decree that the check be made payable to "John Doe"?
