A private citizen is suing Gov. Andrew Cuomo and legislative leaders to try to void expansion of casino gambling approved in June.
A Cuomo spokesman downplayed the lawsuit, saying the governor's actions are routinely upheld in court.
Robert Schulz of Washington County says the bill voted into law on the last day of the legislative session contained dozens of substantive, last-minute changes hidden from public view.
Cuomo says they were only technical changes. He issued a message of necessity that suspended the three days' public review required by the constitution.
Schulz argues Cuomo and legislative leaders negotiated changes involving the payouts and locations of facilities.
Schulz also says an anti-corruption provision that would have limited campaign contributions was dropped.
The Cuomo administration has disputed that, saying it was dropped earlier.
