Case Digest (G.R. No. 241126)
Facts:
In Jasper Tan y Sia v. People (G.R. No. 232611, April 26, 2021), petitioner Jasper Tan was charged before the RTC of Dipolog City with Illegal Sale (Crim. Case No. 11265) and Illegal Possession (Crim. Case No. 11266) of dangerous drugs under Sections 15 and 16, Article III of R.A. 6425. On June 22–23, 2002, during a covert buy-bust operation at his residence’s gate in Miputak, Dipolog City, marked money was purportedly exchanged for sachets of “shabu.” After arresting Jasper and serving a June 21, 2002 search warrant, police recovered additional sachets from his room in the presence of the barangay captain. Laboratory tests confirmed the seized substance as methamphetamine hydrochloride. At trial, two police witnesses testified, while Jasper advanced denial and alleged frame-up. In November 2015, the RTC convicted him, sentencing him to indeterminate terms and fines. The CA affirmed the conviction with modified penalties in its February 14, 2017 Decision. Jasper then filed a RulCase Digest (G.R. No. 241126)
