In New Jersey, for legislative and congressional redistricting, we have bipartisan commissions - an equal number of Democrats and Republicans, with one independent tie-breaker. 

Traditionally, both commissions, either because it is required by the constitution or by custom, hold three public hearings during the process.  

The commissions are required to have geographic diversity in their membership. 

There is no other required public participation component and no other diversity requirement in the makeup of the commissions.
