I have to emphasise that the legal status of the rules of professional conduct in the legal profession made by the General Council of the Bar pursuant to Section 1 of the Legal Practitioners Act, Laws of the Federation of Nigeria 2004 is that of a subsidiary legislation since it is made by provision in a statutory enactment – see Fawehinmi v. NBA (No. 2) (1989) 2 NWLR (Pt. 105) 558 at 614; (1989) 20 NSCC (Pt. 11) 43 at 69. By virtue of Section 18(1) of the Interpretation Act, a subsidiary legislation has the force of law.
