The Supreme Court of Justice of the Nation (SCJN) declared on June 4, 2026, that the requirement to prove at least five years of cohabitation to access a widow's pension from the Mexican Social Security Institute (IMSS) is unconstitutional. ^[1] The Mexican Social Security Institute (IMSS) established a clear parameter stating that a school backpack's weight must be less than 15% of a child's body weight. ^[2] Desirée Sagarnaga, the delegate of the Mexican Social Security Institute (IMSS) in Baja California, acknowledged difficulties in the supply of medications and a backlog in specialist coverage on September 1, 2026. ^[3] The ruling clarifies that while the five-year time limit cannot be used as an automatic barrier, applicants must still prove the existence of a genuine cohabitation relationship through evidence of affection, solidarity, and shared life. ^[4] The SCJN resolved Amparo in Review 408/2025 by a vote of seven, determining that the rigid application of the five-year time limit violates constitutional rights to equality and the protection of different family forms. ^[5] Sagarnaga acknowledged a persistent deficit of specialists, stating that the current backlog is around 5% in specialist coverage. ^[6] Sagarnaga noted that the institute maintains around 1,300 hospitalized people daily and assured that shortages do not prevent treating them in their facilities. ^[7] Sagarnaga stated that medication availability typically ranges between 93% and 94% during major difficulties, while the usual level is around 96%, with an objective to reach at least 98%. ^[8]
