- There were recent guidelines about contract extensions. Please check the GPPB Resolution No. 06-2022 prescribing the guidelines for renewal of regular and recurring services.
- Extension of contract is equivalent to entering into another contract without going through the procurement process, particularly public bidding. (See Capalla v. Comelec, G.R. No. 201112, 13 June 2012). This is more of an exception than the rule that is why this is not encouraged. (See Caltex Ph. v. Delgado Bros., 96 Phil. 368, 375) Amendment to order is also limited so as not to be abused. This is to avoid entering into a contract (after bidding) for specific goods and then substantially amending the contents thereafter. This practice is unfair and forbidden. In Agan v. PIATCO, 402 SCRA 612, 654, the contract with substantial amendment was declared void.
