(1) These Rules apply (with necessary changes) to a cross-claim as if:
(a) the applicant on the cross-claim were the applicant in an original application; and
(b) the respondent to the cross-claim were the respondent to an original application.
(2) However, if a respondent to a cross-claim has an address for service in the original proceeding, service by hand on the respondent is not required.
(3) Subject to rule 24.07, a cross-claim must be heard at the same time as the original application.
