Conn. Practice Book § 67-10 (2026)

Sec. 67-10. Citation of Supplemental Authori- ties after Brief Is Filed When pertinent and significant authorities come to the attention of a party after the party’s brief has been filed, or after oral argument but before decision, a party may promptly file with the appel- late clerk a letter listing such supplemental author- ities, including citations, with a copy certified to all counsel of record in accordance with Section 62-7. If the authority is an unreported decision, a copy of the text of the decision must accompany the filing, unless the authority is an advance release opinion of the Supreme or Appellate Court that is available on the Judicial Branch website or a slip opinion of the United States Supreme Court available on that court’s website. The letter shall concisely state the relevance of the supple- mental citations and shall include, where applica- ble, reference to the pertinent page(s) of the brief. The body of the letter must not exceed 350 words. Any response shall be made promptly and shall be similarly limited. Replies to responses are not permitted. This section may not be used after oral argu- ment to elaborate on points made or to address points not made. All papers shall contain a certification that: (1) a copy has been delivered to each other counsel of record in accordance with the provisions of Section 62-7, and (2) that the letter or response complies with the word count requirement of this section.
