Keep in mind with a lot of the stuff Gov. Cuomo has been doing over the last month when exercising power over the pandemic response would, under normal circumstances, require acts of the Legislature and almost definitely be challenged in court.
The Legislature in March approved a law that funded the initial pandemic response and also granted Cuomo wide latitude in dealing with the crisis. That's why he says he can order when schools reopen in New York City, waive absentee ballot restrictions, etc.
The running update of executive orders Cuomo has issued is below. I don't think there's been a time in the state's history that so many decisions were being made by basically one office. https://www.governor.ny.gov/executiveorders
This isn't to argue they should or shouldn't be made -- but it's an extraordinary exercising of power, even for a governor who has been willing to gain as much leverage as possible in any situation.
