The court may make such orders as will prevent a party from being embarrassed, delayed, or put to expense by the inclusion of another party against whom the party asserts no claim and who asserts no claim against the party, and may order separate trials or may make other orders to prevent delay or prejudice.
Tenn. R. Civ. P. 20.02
Advisory Commission Comments.
Rule 19 deals with situations where certain parties must be joined. Rule 20 deals with permissive joinder. The rule is designed to allow a single suit to determine the rights and liabilities of all persons when those rights and liabilities arose out of the same transaction or occurrence and when a common question of law or fact exists among all parties. Where the liberality of the permissive joinder provisions works a hardship on a particular party or parties, the court is empowered to order separate trials or make other orders necessary to prevent delay or prejudice.
