Date of mailing, filing

The Supreme Court, in the case of Caltex (Phil., Inc. v. Katipunan Labor Union, L-7496, Jan. 31, 1956) held that the petition is considered filed from the time of mailing. This is because the practice in our courts is to consider the mail as an agent of the government, so that the date of mailing has always been considered as the date of the filing of any petition, motion or paper.
