Great question. Here's a quick overview:

CLB (Company Law Board) was the predecessor body before the National Company Law Tribunal (NCLT) was established under the Companies Act 2013. NCLT handles company law matters including insolvency (IBC proceedings), mergers, winding up, etc. NCLAT (National Company Law Appellate Tribunal) is the appellate body where orders of NCLT can be challenged.
