No Extension Can Extend Reply Due Date Beyond Statute Maximum
Note:
This rule states that any extension of time for reply cannot extend the due date beyond the maximum period set by statute.

(b) When a reply cannot be filed within the time period set for such reply and the provisions of paragraph (a) of this section are not available, the period for reply will be extended only for sufficient cause and for a reasonable time specified. Any request for an extension of time under this paragraph must be filed on or before the day on which such reply is due, but the mere filing of such a request will not effect any extension under this paragraph. In no situation can any extension carry the date on which reply is due beyond the maximum time period set by statute. Any request under this paragraph must be accompanied by the petition fee set forth in § 1.17(g).
