The proceeding shall be commenced by filing a petition for review and payment of costs within the time prescribed in Rule 1.100(a). The following instruments shall be attached to the petition for review and to each of its copies:
On compliance with these requirements, the proceeding shall stand perfected and all parties to the proceeding in the tribunal as well as the Workers' Compensation Court shall be considered as parties to the appeal. Any defect in taking a proceeding, other than failure timely to file a petition for review or pay costs, must be disregarded unless a substantial right of the complaining party is affected, and no such defect, if correctable, shall result in dismissal of the appeal.
