To declare, of its own motion, the inadmissibility of submissions, a court is not required to order, beforehand, the reopening of the proceedings.

Practical application:

Under this case law, the court can declare the late appeal inadmissible on its own motion without reopening proceedings. The landlord should compile proof of the decision’s service date and the tenant’s filing date, then formally request the court to rule the appeal inadmissible. Keeping a clear timeline of all notifications and consulting a property lawyer early helps prevent procedural delays.

Practical application:

The ruling confirms a court can reject late submissions on its own motion without reopening the case. The buyer must strictly track all court deadlines and file every supporting document—such as inspection reports, the deed of sale, and correspondence—on time. To avoid losing the case on a procedural technicality, the buyer should calendar reminders and, where possible, seek preventive legal advice before litigation.

Practical application:

Courts may declare such new submissions inadmissible of their own motion without ordering reopening, as confirmed here. The co-owner should prepare all arguments and evidence before filing the initial appeal and adhere strictly to the exchange deadlines set by the judge. If a new issue arises late, he should immediately ask his lawyer whether it can still be admitted, but be prepared for rejection. Preventive consultation with a property specialist before starting the dispute is the safest way to cover all bases.
