Appeal Restriction Following Supplemental Judgment Explanation

The lower court's action of supplementing an incomplete part of its judgment by adding the interest obligation to the principal sum, rather than correcting a manifest error, constituted an explanation under $\S 282$ of the Code of Civil Procedure, which triggered a new deadline for appeal. The reviewing court held that when appealing such an explanatory decision, the appellant is restricted to challenging only the newly explained points, meaning the appeal could only address the awarded default interest and not the unchallenged principal sums or the confirmation of provisional execution orders from the original judgment, as the deadline for appealing those unaffected parts had already expired.
