#Advisory Committee Comment
The exception in this rule acknowledges that there are different rules that apply to certain nonconforming documents. For example, this rule does not apply to nonconforming or late briefs, which are addressed by rules 8.204(e) and 8.220(a), respectively, or to nonconforming supporting documents accompanying a writ petition under chapter 7, which are addressed by rule 8.486(c)(2).
