I'm pretty confident I should know this, but here it goes. Do the joinder rules apply only to "claims" or do they also apply for "causes of action."

For example, if a dude files a complaint and lists 5 causes of action with several different parties, do the joinder rules need to be met at this time? Or, do you only apply the joinder rules if another claim/party is added after the initial complaint?

Thanks in advance!

Is the plaintiff trying to bring all five causes of action in one claim? If so, Rule 20 would likely cover this sort of thing. Atleast as far as I can tell...Its like joining defendants. I don't have my rules in front of me at the second but if they arise out of the same facts, I think you can do this sort of thing as long as it doesn't screw up your SMJ.

Look at FRCP 18(a) and 20(a)(2)
