Rule 22 Acknowledgment by respondent
Each respondent who intends to participate in the appeal must file notice of intention to participate.
The notice of intention to participate in the appeal must be filed within 14 days after—
service of the notice of intention to proceed under rule 19(2); or
service of the notice of appeal under rule 21(2).
A respondent who wishes to argue that the order appealed from should be upheld on grounds different from those relied on by the court below, must state that clearly in the notice of acknowledgment (but need not cross-appeal).
Each respondent must within 7 days of filing the notice under paragraph (1) serve that notice on the appellant and any other respondent.
A respondent who does not file and serve notice under this rule will not be permitted to participate in the appeal and will not be given notice of its progress.
