In this slip-and-fall action, defendant Milleridge Inn, Inc. (Milleridge or defendant) appeals from the IAS Court's sua sponte decision to sever the third-party action. Third-party defendant Maura Brothers Company, Inc. (Maura Brothers) has not appeared on this appeal. Counsel for plaintiff Karen Rothstein (Rothstein or plaintiff) has filed a letter taking no position on the severance issue.

Plaintiff was injured when she slipped and fell on ice and snow in the parking lot of defendant's restaurant on January 8, 1994. She filed a summons and complaint on October 29, 1996. Issue was joined on December 19, 1996.

Pursuant to the court's preliminary conference order of May 28, 1997, impleader actions were to be commenced within 60 days of completion of the parties' depositions. On November 5, 1997, defendant commenced the third-party action by filing a third-party summons and complaint against Maura Brothers, the contractor hired by defendant to remove snow and ice from the parking lot at the time of the accident. It is not argued that defendant failed to comply with the time limits set forth in the preliminary conference order.

Moreover, by the time the parties appeared before the court for a compliance conference on December 2, 1997, discovery in the primary action was complete. Maura Brothers had not served its answer, but its time to answer had not yet expired. (The third-party answer was filed on December 31, 1997, pursuant to a stipulation extending the time to answer.) Though none of the parties had expressed any concern that they would be prejudiced if the actions were tried together, or requested severance, the court sua sponte severed the third-party action, over the defendant's objection. We find that this severance was an improvident exercise of discretion.

Severance of a third-party action is within the discretion of the trial court. However, severance is inappropriate absent a showing that a party's substantial rights would otherwise be prejudiced ( Andresakis v. Lynn, 236 A.D.2d 252). To avoid the waste of judicial resources and the risk of inconsistent verdicts, it is preferable for related actions to be tried together ( Shanley v. Callanan Indus., 54 N.Y.2d 52, 57), such as in a tort case where the issue is the respective liability of the defendant and the third-party defendant for the plaintiff's injury ( Dolce v. Jones, 145 A.D.2d 594, 595).

In a case where the main action was trial-ready but still-outstanding discovery on the third-party action would unreasonably delay bringing the plaintiff's case to trial, a joint trial of the main and the third-party actions could prejudice the plaintiff ( Pena v. City of New York, 222 A.D.2d 233). Here, Rothstein has never stated that she feared prejudicial delay would result from a joint trial. By contrast, the court's decision to sever the third-party action would prejudice defendant Milleridge. The trier of fact cannot properly determine whether Milleridge negligently maintained the parking lot without considering whether Maura Brothers used due care in performing the snow and ice removal ( see, Karama Supermarket v. Frawley Plaza Assocs., 200 A.D.2d 355, 356).
