| Petitioners further assert that the policy guidelines are invalid for having been applied retroactively. According to petitioners, the ERC applied the policy guidelines to periods of PPA implementation prior to the issuance of its 14 January 2005 Order.[101] In Republic v. Sandiganbayan,[102] this Court recognized the basic rule "that no statute, decree, ordinance, rule or regulation (or even policy) shall be given retrospective effect unless explicitly stated so."[103] A law is retrospective if it "takes away or impairs vested rights acquired under existing laws, or creates a new obligation and imposes a new duty, or attaches a new disability, in respect of transactions or consideration already past."[104] | |||||
