“Any number of claimants or defendants may be joined as parties to a claim.”
“I turn next to the question of whether any of the three tests promulgated in Abbott are correct. I have described the three tests as the real progress test, the real significance test and the test that requires that the determination of common issues in a claim by multiple claimants under 19.1 would bind all parties. I do not think any of these tests is appropriate to exclude cases from the ambit of 19.1. It seems to me that 19.1 and 7.3 must be construed as meaning what they say: any number of claimants or defendants may be joined as parties to proceedings, and claimants may use a single claim form to start all claims which can be conveniently disposed of in the same proceedings. There is no exclusionary rule of real progress, real significance or otherwise. The court will determine what is convenient according to the facts of every case.”
