Lumanlaw v. Peralta, Jr.

Summary

This landmark case established that prolonged delays in arraignment violate the constitutional right to speedy trial, particularly when the accused remains detained. Petitioner Lumanlaw, charged with drug possession, endured fourteen postponements over nearly two years without arraignment due to administrative failures, absent parties, and poor court management. The Supreme Court granted mandamus, dismissing the criminal case and ordering petitioner's release. The Court emphasized that while some delays may be reasonable (judge's retirement, preliminary investigation requests), the majority of postponements were unjustified and could have been avoided through proper judicial administration. The decision reinforced that arraignment is not mere formality but integral to due process, and judges must actively manage proceedings to prevent constitutional violations. The case serves as precedent for using mandamus to compel speedy trial compliance and underscores judicial responsibility in protecting constitutional rights of detained accused persons.
