The UP Law Faculty is known for its expertise in a variety of fields such as constitutional law, intellectual property, international law, environmental law, information technology, gender and human rights. Policy makers call on the faculty regularly for their insights on pending legislation or to draft laws for congressional action. Members of the faculty litigate cases of national significance including the issues revolving around the Maguindanao massacre and the Cybercrime Prevention Act. They appear before the Supreme Court either as counsels for various parties or as amicus curiae. Chief Justice Ma. Lourdes Sereno and Associate Justice Marvic Leonen were part of the faculty for many years. Outside of the country, several members have held notable positions: among the most recent is Dean Raul C. Pangalangan, who currently serves as a judge for the International Criminal Court.

The faculty is also widely published in prestigious journals in the Philippines and in other countries.

Among the faculty are recipients of prestigious awards such as the Ten Outstanding Young Men (TOYM) and the Ramon Magsaysay Award.
