Given the increasing number of foreigners residing in ABC City, its Sangguniang Panlungsod issued Ordinance No. 0628, allowing foreigners who have resided for at least five years in the City to acquire ownership over parcels of land not exceeding 500 square meters.

ABC City, on the other hand, argued that it was granted local autonomy within its jurisdiction and can therefore pass any ordinance it deems beneficial to its residents. Decide with reason(s).
