Supreme Court Rules 2000

A defendant in an action may file and serve on another defendant in that action a notice claiming contribution, indemnity or any relief or remedy relating to, or connected with, the original subject matter of the proceeding and substantially the same as some relief or remedy claimed by the plaintiff.

A defendant in an action may file and serve on another defendant in that action a notice specifying any question or issue relating to, or connected with, the original subject matter which – is substantially the same as a question or issue arising between the plaintiff and the defendant making the claim; and should properly be determined not only as between the plaintiff and the defendant making the claim, but as between the plaintiff and that defendant and another defendant, or between any of them.

A notice of appearance is not required to be filed to a notice under subrule (1) or (2).

The same procedure is to be adopted for the determination of a claim raised by a notice under subrule (1) or (2) as if the defendant to whom the notice is given were a third party.
