A Bullock or Sanderson order may be made where the causes of action against multiple defendants are not identical but are substantially connected or dependent on one another. In vicarious liability cases, the claim against the employer is sufficiently connected with the tort claim against the servant because the plaintiff cannot reach the employer without first proving the servant's tort. Four conditions must be satisfied: (1) the plaintiff acted reasonably in joining the successful defendant; (2) the causes of action are substantially connected or dependent; (3) the conduct of the unsuccessful defendant makes the order a proper exercise of discretion; and (4) the court must balance the policy against forcing unnecessary multiplicity of actions against the policy that an unsuccessful defendant should not have to pay more than one set of costs.
