A subpoena is a writ commanding a person designated in it to appear in court under a penalty for failure. A subpoena duces tecum, on the other hand, is a writ commanding a person to produce in court certain designated documents or evidence. The new law came a little over a month after the PNP relaunched its anti-drug operation Double Barrel, vowing that the operation would be less bloody. Under Lower Barrel of the operation, the police convince drug suspects to surrender to authorities. The President pulled out the PNP from anti-drug operations in October 2017, replacing it with the Philippine DrugEnforcement Agency (PDEA).
