Federal Rules of Civil Procedure

(a) Consolidation.

If actions before the court involve a common question of law or fact, the court may:

(1) join for hearing or trial any or all matters at issue in the actions;

(2) consolidate the actions; or

(3) issue any other orders to avoid unnecessary cost or delay.

(b) Separate Trials.

For convenience, to avoid prejudice, or to expedite and economize, the court may order a separate trial of one or more separate issues, claims, crossclaims, counterclaims, or thirdparty claims. When ordering a separate trial, the court must preserve any federal right to a jury trial.
