New York, NY —
A state court wasn't friendly to their cause, so opponents to the way the city's term limits law was changed have gone to federal court.
REPORTER: Attorney Norman Siegel says federal courts have ruled against elected officials who try to keep themselves in power.
SIEGEL: If you can show that their actions are 'patently and fundamentally unfair.' Then you have a due process violation.
REPORTER: The lawsuit is being brought by a group of elected officials that includes City Comptroller Bill Thompson and the Republican former Staten Island borough president Guy Molinari.
Several teachers have also filed a federal lawsuit...to block the term limits extension.
The city's law office says the claims are without merit.
