PRINCIPLE STATEMENT

What makes a ground of appeal incompetent is not whether it is framed as an error and a misdirection but whether by so stating it the other side is left in doubt and without adequate information as to what the complaint of the appellant actually is; notwithstanding the formulation of the grounds of appeal that were struck out, the detailed statement of the particulars of error and the clear statements of what the appellants conceived to be errors in law and misdirection in fact in the judgment of the trial judge, satisfied the requirement of the rule as to formulation of grounds of appeal; to hold otherwise will be tantamount to insistence on form rather than substance.

EXPLANATION / SCOPE

Ground competence depends on notice adequacy, not formal wording. Incompetence test: Does ground leave respondent: in doubt about complaint, without adequate information, or unclear what appellant’s actual grievance is? If yes—incompetent. If no—competent. Form vs. substance: Ground alleging both “error of law” and “misdirection” isn’t automatically incompetent merely for dual characterization—if particulars provide clear information about complaint, ground satisfies requirements. “Detailed statement of particulars” and “clear statements” of perceived errors: satisfy formulation requirements, give adequate notice, and enable respondent to understand and meet appeal. This serves: substance over form, preventing technical striking out of adequately particularized grounds, and ensuring respondents receive meaningful notice. “Tantamount to insistence on form rather than substance” means: focusing on wording style while ignoring whether purpose (notice) is achieved. Courts must assess: does ground (with particulars) adequately inform respondent? can respondent understand complaint? does it enable meaningful response? If yes: ground is competent regardless of imperfect formulation. Purpose matters: Rules exist to provide notice—any ground achieving that purpose should survive even if not perfectly worded. However: vague grounds without particulars remain incompetent—particulars/clear statements are what cure potential formulation defects. This principle prevents: technical striking out of substantially compliant grounds, form triumph over substance, and defeating appeals on labeling rather than content adequacy.
