In law when an appeal against the decision of the Court below, the National Industrial Court of Nigeria, borders squarely on allegation of any breach of Chapter IV of the Constitution of Nigeria 1999 (as amended) dealing with the provisions relating to fundamental rights, such an appeal lie as of right and no leave of Court is required. So also is an appeal against the decision of the Court below in criminal matters lie as of right without any need for leave of Court. However, where an appeal against the decision of the Court below in civil matter borders on grounds other than grounds alleging breach of any of the provisions of Chapter IV of the Constitution of Nigeria 1999 (as amended), happily the law is now firmly settled that it can only lie with the leave of Court. See Skye Bank v. Iwu (2017) LPELR-42595 (SC).
