The binding legal principles established include: (1) Municipal by-laws enacted under section 156 of the Constitution governing land use and planning remain valid and applicable even in the context of telecommunications infrastructure deployment under the ECA; (2) Section 22 of the ECA, which grants rights to electronic communications network service licensees to enter land and construct facilities, must be interpreted harmoniously with municipal planning powers rather than as automatically overriding all municipal regulatory requirements; (3) Courts must prefer reasonable interpretations that avoid conflict between national and municipal legislation over interpretations that result in conflict, as required by principles of cooperative governance under section 41 of the Constitution; (4) The constitutional model of distinct, interdependent and interrelated spheres of government requires that each sphere respect the status, powers and functions of the other spheres; (5) Municipal planning, as a functional area listed in Part B of Schedule 4 to the Constitution, includes zoning of land and gives municipalities legitimate regulatory authority that must be respected by other spheres of government.
