Top Courts Reshape Peru's Corruption Probes

Recent decisions from the Constitutional Court and the Supreme Court change pretrial detention rules and judge oversight in major cases, raising tensions between courts, prosecutors and police.

Overview

  • The Constitutional Court announced rulings made public Wednesday that annulled Vladimir Cerrón’s 24‑month preventive detention and ordered the suspended judge Richard Concepción Carhuancho removed from the Nicanor Boluarte case for compromising impartiality.
  • The Supreme Court’s Penal Chamber confirmed a separate decision to extend former president Pedro Castillo’s preventive detention by 12 months, keeping him jailed through March 2027 because judges found a continued flight risk and complex forensic work remains.
  • The TC also allowed the Public Ministry to join Ollanta Humala’s habeas corpus as a participating party, a move that gives prosecutors a formal voice in the constitutional review that could affect his criminal case.
  • Police chief Óscar Arriola defended multiple warranted search operations used to try to find Cerrón and said officers entered nine to ten properties, while Cerrón’s mother publicly insisted he stayed in Huancayo during his time in hiding.
  • The rulings expose growing institutional friction: the TC is using habeas corpus and impartiality standards to alter detention and judge assignments while ordinary courts and the JNJ maintain suspensions and extended detentions, a pattern that will force prosecutors and judges to reframe risk assessments and enforcement plans.
