proposition two and a half
As the mentioned here, the most famous Massachusetts initiative petition is known as “Proposition 2 1/2”, which just happens to be a perfect example of the fusion between the state and local level I&R processes in the Commonwealth. Ever since Prop. 2 1/2 passed in 1982, voters in a municipality must pass a “Proposition 2 1/2 override” to increase property taxes beyond 2.5% of the assessed value of all taxable property contained in it the municipality. Towns rarely do pass Prop. 2 1/2 overrides.
