Tribunal jurisdiction expanded to specified matters, allowing legislatures to establish tribunal hierarchies and procedural rules. Article authorises the appropriate Legislature to provide for tribunals to adjudicate disputes, complaints and offences in enumerated subjects (tax administration, foreign exchange and customs, industrial and labour disputes, land reform and ceilings, certain electoral matters, essential goods and price control, rent and tenancy, related offences and incidental matters). A law under this power may create a hierarchy of tribunals, specify jurisdiction and powers including contempt, set procedures (including limitation and evidence), transfer pending cases, exclude court jurisdiction except the Supreme Court under article 136, and make necessary supplemental and consequential provisions.
