PARTIES IN SAME APPEAL BEFORE THE SUPREME COURT WHO ARE UNITED IN INTEREST SHOULD FILE A JOINT BRIEF
In Abubakar v. Providus Bank Ltd. (2026) 13 NWLR (Pt. 2056) 87 at 140—141, D—A per Abubakar JSC: ‘The jurisprudential rationale behind Order 16 rule 7(1) of the Supreme Court Rules, 2024 is self-evident. Where parties are united by common interest and pursue identical reliefs or legal objectives, multiplicity of briefs serves no legitimate purpose. Rather, it clogs the appellate process with repetitive submissions, burdens the opposing party with needless responses, and dissipates valuable judicial time that ought to be devoted to the determination of genuinely contentious issues. The law does not encourage superfluity. Equity, like nature, abhors multiplicity where unity suffices. The mandatory tenor of the Rule is underscored by the deliberate use of the word ‘shall’. It is elementary that where the word ‘shall’ is employed in a statutory or procedural provision, particularly in relation to a duty imposed upon litigants, it ordinarily imports compulsion and not mere discretion, unless the context otherwise admits. See Access Bank Plc v. Ogboja (2022) 1 NWLR(Pt. 1812) 547. The obligation imposed on parties with identical interests to file a joint brief is therefore mandatory. In the instant appeal, not only are the interests of the respondents visibly aligned, but the arguments also advanced in their separate briefs are virtually indistinguishable in contents, reasoning, and relief sought. No conflict of interest has been demonstrated. No divergence in legal position has been disclosed.No peculiar defense or separate factual matrix has been identified to justify the filing of multiple briefs. The separate briefs merely reproduce, in repetitive sequence, the same preliminary objections and substantive submissions. Such a course of conduct runs contrary to both the letter and spirit of Order 16 rule 7(1) of the Rules of this court.’
