Citation of Supplemental Authorities.
If pertinent and significant authorities come to a party's attention after all original and reply briefs have been filed - or after oral argument but before decision - a party may promptly advise the clerk by letter, with a copy to all other parties, setting forth the citations. The letter shall be limited to:
(a) the name and citation of the opinion or authority; (b) the issue raised by the case which is pertinent to the issues raised in the case pending before this Court; and (c) a citation to the page number of where this point has been raised in briefs before this Court or, if not raised in briefs and dealt with in oral argument only, where and how this issue arose during oral argument. The body of the letter shall not exceed 350 words. Any response must be made promptly and must be similarly limited. No response to the response shall be allowed. This Section 11.2 letter shall not contain argument; if a party desires to make an argument or to exceed 350 words, the party shall file a motion for permission to file a supplemental brief pursuant to Section 11.1 of this Rule.
