1. ABC Construction Company was engaged by XYZ Group Inc. to build an eight- storey building with a height of 34.4 meters located behind the intended new airport in Bulacan. A month later, Ordinance No. 12345 was passed by the Sangguniang Panlalawigan of Bulacan, setting the height limit on the buildings to be constructed along the new airport to five storeys or a maximum height of 21.5 meters. After building five storeys, ABC Construction Company served a notice on XYZ Group Inc. that it can no longer build the sixth, seventh, and eighth floors of the building in view of Ordinance No. 12345. XYZ Group Inc. consequently assailed Ordinance No. 12345 for allegedly violating the non-impairment clause of the Constitution. Will the case prosper? Reason(s).
