The management of extensions by the Caja of Seguro Social is based on the provisions established in both current Law 22 of June 27, 2006, which regulates Public Procurement, and Law 51 of December 27, 2005, of the Caja of Seguro Social, which establish the legal framework to regulate the extension of contracts within the institution. In this context, we will focus on extensions authorized under Law 51, which grants the Caja of Seguro Social the exorbitant power to extend contracts through extension documents, legally equating them to an addendum to the contract. This prerogative allows adjusting the term of the contracts; however, there are differences in the processing of extensions, especially in cases where fines are not imposed. In accordance with Law 51, in cases of force majeure or unforeseeable circumstances, suppliers can request extensions without penalty. Furthermore, when the cause of the delay is attributable to the entity, extensions will also be granted without fine. This work describes the most relevant aspects of the processing of extensions without fines in the Caja of Seguro Social, detailing the criteria, authority and authorizations in which these extensions can be requested without incurring penalties.
