Definition
A historical common law writ directed to justices commanding them to affix their seals to exceptions formally raised by a defendant against a plaintiff's evidence, verdict, or other proceedings before them. The writ derived its authority from the Statute of Westminster II (13 Edw. I, St. 1, c. 31), which established the formal mechanism by which a party could preserve exceptions — essentially objections — for appellate review by requiring the presiding justice to authenticate those exceptions under seal.
In practical terms, a defendant who wished to challenge some aspect of the evidence, verdict, or proceedings against him needed the trial court's seal affixed to his bill of exceptions to give it legal force. If a justice refused or neglected to seal the exceptions, the writ of ponendum sigillum ad exceptionem compelled him to do so. Without the seal, the exceptions could not be formally presented to a superior court.

Common Confusion
This writ is procedurally related to, but distinct from, the bill of exceptions itself. The bill of exceptions was the written record of the objection; ponendum sigillum ad exceptionem was the enforcement mechanism used when a justice failed voluntarily to authenticate that bill. Researchers should not conflate the two: one is the substantive document preserving the objection, the other is the coercive writ compelling its formal validation.

Why It Matters in Research
This term belongs to a narrow class of auxiliary common law writs that enforced procedural obligations on judicial officers rather than on parties. Researchers working in medieval and early modern English legal sources will encounter it almost exclusively in writ registers, procedural treatises, and statutory commentary on Westminster II — not in case law in the conventional modern sense.
The Statute of Westminster II (1285) is the essential anchor for understanding this writ. Chapter 31 of that statute created the formal right to a bill of exceptions, and ponendum sigillum ad exceptionem was the corresponding enforcement mechanism built to give that right practical effect. Any research into the development of appellate practice, the bill of exceptions as a procedural device, or the evolution of judicial accountability in English common law should treat this writ as contextually important even if rarely named directly.
The hyphenated spelling in the source heading (Ad Excep-Tionem) is a typographical artifact of older print editions and should not be treated as an alternate form. Researchers searching historical writ registers or digitized legal texts should search the unhyphenated Latin form.
Because this writ functioned only so long as the bill of exceptions required judicial sealing for validity, it became obsolete as procedural reforms eliminated the sealing requirement. American practice adopted the bill of exceptions through common law reception but the English writ machinery behind it — including this writ — did not transfer in any operative sense. Researchers in American legal history will find the bill of exceptions itself transplanted; the writ compelling its sealing belongs firmly to English legal history.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed., Supplemental) provides the only dictionary entry in the Law Mind corpus for this term, defining it as a writ requiring justices to seal exceptions exhibited by a defendant against a plaintiff's evidence, verdict, or other proceedings, with direct reference to the Statute of Westminster II as the statutory foundation. The entry is brief but accurate in its structural description.
No other source dictionaries in the Law Mind corpus cover this term, which reflects its narrow procedural specificity and its obsolescence following the decline of sealing requirements. Black's characterization aligns with what is known from English legal history about the function of the writ. Researchers should note that Black's gives the defendant as the party whose exceptions are at issue — historically accurate, as it was typically a defendant seeking to preserve objections to proceedings against him, though the logic of the writ would not have been categorically unavailable to a plaintiff in procedurally analogous circumstances. The entry does not address this edge, and no supplementary corpus source resolves it.

Jurisdictional Note
This writ is exclusively an English common law instrument rooted in statute. It has no American equivalent and no operative counterpart in any modern jurisdiction. Its relevance is historical and comparative only.
