There is value in an appellate court that reaches the right destination under pressure; but in adjudication the route is not a detail. When, say, a court limits an appeal to a preliminary point, that boundary becomes part of the case’s legal architecture. It shapes what the parties prepare, what they argue, and what they reasonably expect will be decided. Respecting that frame is not formalism; it is the method by which reasons are built and remain trustworthy the day after judgment is delivered. In the recent case in the names Patrick Guntrip vs L-Awtorità tal-Ippjanar, that lesson was made plain: once argument is confined to a preliminary plea, deciding the merits without hearing the parties on those merits undermines the fairness of the process.

Some foundational principles follow.

First, audi alteram partem demands a real opportunity to be heard on the issue that will be determined. A hearing about jurisdiction or prescription cannot silently mutate into a merits adjudication. If the scope must widen, the parties must be recalled and invited to address the new terrain.

Second, ultra (extra) petita is not a relic; adjudicators do not decide points the parties were not called to meet, nor do they import evidence from elsewhere without putting it to the parties.

Third, procedural self-binding matters: when a tribunal frames the case through a decree—limiting issues, setting a sequence, or identifying an exception—that decree is part of the parties’ legitimate expectations and should be followed unless varied openly and with reasons.

Fourth, reasoned decision-making requires that the outcome rest on the record of the case, not on materials drawn from parallel files or assumptions never tested in submissions.

Fifth, harmless error has limits: some defects are structural because they impair participation at the decisive moment; such errors are not cured by assurances that “the result would have been the same.”

This discipline applies equally at the lower realms. The Planning Board and the Planning Commission are bound by the issues as properly framed, by their own directions during sittings, and by the written stipulations governing filings, site submissions, and policy application.  The Environment and Planning Review Tribunal, entrusted with a tightly structured statutory mandate, must be stricter still: it should keep to what is within its appellate compass, decide on the record of the appeal, and avoid blending evidence or reasoning from separate appeals unless parties are heard on the integration.

One final word –  equity does not dissolve these requirements. Appeals to broad “fairness” or “overall justice” cannot excuse short-circuiting the framework that fairness presupposes. Equity is a complement to law, not a licence to bypass it. If a board, commission, or tribunal believes the frame should widen, the lawful path is simple: call the parties back, state the intended variation, invite submissions, and decide on the record thus constituted. One may approve of the destination—and perhaps the merits will lead there again—but the path matters.
