The position of the law is well settled that no cause or matter shall be defeated by reason of mis-joinder or non-joinder of parties and the Court may in every cause or matter deal with the matter in controversy so far as regards the rights and interest of the parties actually before it.
CHIEF EMMANUEL BELLO v. INDEPENDENT ELECTORAL COMMISSION & ANOR.(LGC(/5/3/2010)N-O
There is a settled line of authorities to the effect that the domestic or internal affairs of a political party are not Justiciable, that the Courts will not dabble into the membership of a party or who it chooses to sponsor for an election. See: Onuoha Vs Okafor (1983) 2 SCNLR 244; P.D.P Vs Sylva (2012) 13 NWLR (Pt. 1316) 85; APGA Vs Anyanwu (2014)1-2 SC (pt. 1) 1; Emenike Vs P.D.P (2011) LPELR 1975 2(CA).
However, in making its choice, a political party must act within the law and must comply with its own constitution and guidelines. Prior to 2006 political parties acted with impunity in the selection, sponsorship and substitution of candidates for election.
