Can appellate counsel who wish to raise the issue of inadequate trial representation join a verified petition for writ of habeas corpus?

appellate counsel who wish to raise the issue of inadequate trial representation should join a verified petition for writ of habeas corpus."' [Citations.] Because claims of ineffective assistance are often more appropriately litigated in a habeas corpus proceeding, the rules generally prohibiting raising an issue on habeas corpus that was, or could have been raised on appeal [citations] would not bar an ineffective assistance claim on habeas corpus."
