I was unaware (until now) that it was in the state constitution. In NJ, a few districts have done this or threatened to do this to pass the budget.
Here is what I found on the NY website:

The mileage marker is 2 miles or greater. When I lived in Monsey, I got busing to school that was less than a mile. They could raise the requirements to match the state mandate.
That’s not to say voting for a budget increase is the right thing to do. I just don’t think this call for everyone enmasse to vote down the budget makes sense.
