Rule 17 of the Constitutional Court Rules is a procedure for gaining direct access to the Constitutional Court in circumstances where an issue has not been considered by another court, and may only be employed in exceptional circumstances. It is not an appeal procedure and may not be used for disguised appeals. Where an applicant seeks to appeal a conviction, the proper procedure is to approach the Court under rule 18, not rule 17. The Court will not overlook improper procedural choices, particularly where the applicant is legally represented.
