For all development proposals, a municipality:

The correct answer is rooted in the principles governing land use and development review in New Jersey. Municipalities are required to adhere to established zoning rules and regulations at the time they receive a development application. This ensures that applicants have a clear understanding of the regulatory environment in which they are operating, promoting fairness and consistency in the development review process.

Amending zoning during the application review process can create significant uncertainty and can disadvantage applicants who have invested time and resources based on existing regulations. New Jersey law aims to prevent municipalities from making changes in order to directly respond to specific development proposals, ensuring that zoning amendments reflect broader community needs and not just individual applications.

Furthermore, the judiciary does not typically engage in evaluating the wisdom of zoning changes as they pertain to individual applications. Instead, the courts focus on the legality and procedural propriety of zoning decisions. This separation maintains a checks and balances approach to land use planning.

Thus, none of the stated options accurately reflect the legal framework or best practices regarding the handling of development proposals in New Jersey, making "none of the above" the correct choice.
