Mandaluyong instance of highly urbanized city
Cityhood
By virtue of the 1987 Constitution, Mandaluyong and the then-municipality of San Juan were represented in Congress by a single congressman.
San Juan–Mandaluyong Rep. Ronaldo Zamora sponsored a House Bill which eventually became Republic Act No. 7675 otherwise known as "An Act Converting the Municipality of Mandaluyong into a Highly Urbanized City to be known as the City of Mandaluyong." President Fidel V. Ramos signed R.A. No. 7675 into law on February 9, 1994 (the 49th anniversary of its liberation from the Japanese), which was ratified through a plebiscite on April 10, 1994, making Mandaluyong the fifth city in Metro Manila. Mandaluyong became a lone district with its own representative in Congress. Prior to the enactment of the assailed statute, the municipalities of Mandaluyong and San Juan belonged to only one legislative district.
