Charlie,
According to the New York State Unified Court System website (an official NYS Court site), The Constitutional Convention of 1967 was submitted to the voters as entire package, rather than allowing voters to vote on individual iterms proposed to change. In other words, voters could “take it or leave it”. If they had approved it, amongst other things, they would have in addition to any changes to the Blaine Amendment:
* provided for the gradual state takeover of the statewide court system
* added authority for cooperative financing among multiple local governments
* required the gradual transfer to the state of the administration and cost of local welfare programs; and allowed the legislature to incur debt without a voter referendum
In other words, this was far more than just the Blaine Amendment. And voters did not like the package deal.
