Overview
- The dispute began when a retaining wall related to construction at Simone Mendes's Barueri property collapsed on November 6, 2024, sending water, mud and debris into neighbor Léo Stuart’s home and damaging outdoor areas and a piano.
- Court-appointed experts found Simone’s retaining wall lacked drainage and adequate structure, saying saturated soil acted like a ‘barragem’ that pushed the neighboring wall to failure.
- Simone’s defense says the collapse was caused by exceptional heavy rains, notes the work was carried out by a contracted company, and submitted a private engineering report that blames the neighbor’s wall.
- A lower-court injunction ordered immediate suspension of the work and reconstruction within 30 business days with daily fines, the TJ-SP upheld those urgent measures and later rejected embargos, and Simone’s lawyers filed a Recurso Especial to take the case to the STJ.
- The case is still pending procedural steps at the higher court, enforcement of repairs has not been completed, a July 21, 2026 conciliation hearing did not occur because Simone and her lawyers were absent, and the unresolved injunction raises concern about new storm damage and proof preservation.
