Cuomo said Wednesday he'll create a panel under the state's powerful Moreland Act to investigate lawmakers because of the latest string of corruption cases.
But the state Attorney General's Office and academic Richard Brodsky say Thursday the law doesn't allow the executive branch to directly investigate another branch.
Cuomo says he can avoid that prohibition by investigating through the Board of Elections.
And two think tanks say a binding arbitration measure meant to help financially strapped cities dropped strong language to protect taxpayers to favor powerful unions.
Cuomo has rejected those arguments.
Both are expected to pass into law by Friday when the 2013 session ends.
