Colombia's Constitutional Court upheld approximately 90% [1] of President Gustavo Petro's pension reform law, known as Law 2381 [1].

The ruling provides a significant victory for the Petro administration but creates a legislative hurdle for the remaining portions of the law. Because the court identified procedural irregularities, Congress must now revisit specific sections to ensure they meet constitutional standards.

Magistrate Paola Andrea Meneses and the court said that certain parts of the reform lacked proper debate. As a result, the court returned between nine [3] and 10 [4] articles to Congress for revision. The discrepancy in the number of returned articles stems from differing reports by RCN and La FM.

The court's decision follows a review process that resumed on Jan. 13, 2026 [5]. The ruling specifies that the reform will become effective on April 1, 2027 [4].

The articles sent back to the legislature were flagged for procedural shortcomings. The court said that these specific sections did not follow the required legal steps during their initial passage through Congress [6].

While the majority of the framework remains intact, the administration must now navigate the legislative process again to secure the remaining articles. The court's action ensures that the final version of the law adheres to the country's constitutional mandates regarding legislative debate.

The Constitutional Court upheld approximately 90% of President Gustavo Petro's pension reform law.

This ruling represents a strategic compromise by the Colombian judiciary. By upholding the bulk of Law 2381, the court maintains the momentum of the government's social agenda while asserting its role as a check on legislative haste. The requirement for Congress to re-debate specific articles prevents the government from bypassing constitutional procedural norms, potentially opening the door for opposition lawmakers to negotiate changes to those specific sections before the 2027 implementation date.
