Notwithstanding any other provision of this chapter, a municipality has no less authority to adopt or apply laws and regulations concerning zoning, land use planning, traffic management, urban nuisance, or historic preservation than the authority of the municipality that existed under the law as interpreted by the federal courts before April 17, 1990. This chapter does not affect the authority of a municipality to adopt or apply laws and regulations as that authority has been interpreted by any court in cases that do not involve the free exercise of religion.
