The Flag Law or Act No. 1696, passed on 6 September 1907, proscribed the Philippine flag or any nationalist flags, banners or symbols, particularly those identified to the Katipunan, and banned the use of the Philippine national anthem. This law was repealed in 1919.
It was brought about in view of the fact that in processions held in Manila, Caloocan, and Navotas for the purpose of celebrating the triumph of one of the political parties occasion was taken to relegate the American flag to second place or to the rear of the processions and to display an American flag of so small a size as to make it ridiculous when compared with insurrectionary flags, banners, and emblems carried in the post of honor.
