DECISION ORDER

ORDERED that the order is reversed, on the law, without costs or disbursements, and the matter is remitted to the Supreme Court, Suffolk County, for a new determination of the motion and cross motion following a prompt application to the Workers' Compensation Board to determine the parties' rights under the Workers' Compensation Law.

The injured plaintiff, a student at Dowling College, was injured while serving as a student teacher in a high school operated by the defendant Half Hollow Hills Central School District. The relevant statutes (see e.g. Workers Compensation Law §§ 2, 3 [1] [Group 20-a], [Group 22]) are not so clear as to warrant the conclusion that, as a matter of law, the plaintiff was an employee of the defendant Half Hollow Hills Central School District so as to preclude her from bringing an action at law against that defendant (see Workers' Compensation Law §§ 11, 29). Because the relevant statutes are less than explicit in defining whether the plaintiff was an employee for the purpose of rendering her eligible for workers' compensation benefits, "the appropriate course [is] to await a conclusive determination by the Workmen's Compensation Board" (O'Rourke v. Long, 41 N.Y.2d 219, 224; cf. Matter of Scatola, 257 A.D. 471, affd 282 N.Y. 689; see also Botwinick v. Ogden, 59 N.Y.2d 909; Kayen v. Shames Realty, 298 A.D.2d 362; White v. Marriott Mgt. Servs., 283 A.D.2d 639; Melo v. Jewish Bd. of Family Children's Servs., 282 A.D.2d 440; Bohorquez v. Rikud Realty, 280 A.D.2d 628; Manetta v. Town of Hempstead Day Care Ctr., 248 A.D.2d 517).

The question whether a particular person is an employee within the meaning of the workers' compensation statutes is "usually * * * a question of fact to be resolved by the [Workers'] Compensation Board" (O'Rourke v. Long, supra at 224, citing Matter of Gordon v. New York Life Ins. Co., 300 N.Y. 652; see also Firestein v. Kingsbrook Jewish Med. Center, 137 A.D.2d 34, 41). In deciding a motion addressed to the validity of a workers' compensation defense interposed by a defendant in a personal injury action, a court may properly decide the question of the plaintiff's eligibility for worker's compensation benefits only where the applicable statutes are unambiguous, and where such question is therefore one of pure law (see O'Rourke v. Long, supra at 224).

We reject the approach, reflected in certain prior cases (e.g. Croston v. Montefiore Hosp., 229 A.D.2d 330; Olsson v. Nyack Hosp., 193 A.D.2d 1006; Galligan v. St. Vincent's Hosp., 28 A.D.2d 592), according to which a court may make such a determination, without deference to the Workers' Compensation Board's primary jurisdiction (see Botwinick v. Ogden, supra; Kayen v. Shames Realty, supra; White v. Marriott Mgt. Servs., supra), based on its own assessment of the facts, or based on its own balancing of various factors, rather than as a pure question of law. Such an approach has been described by the Court of Appeals as "inappropriate" (Botwinick v. Ogden, supra at 911; see also Kayen v. Shames Realty, supra; White v. Marriott Mgt. Servs., supra). In any event, the present case is distinguishable on its facts from Croston v. Montefiore Hosp. (supra), Olsson v. Nyack Hosp. (supra), and Galligan v. St. Vincent's Hosp. (supra).

The record does not support the plaintiffs' argument that the defendants wilfully refused to provide pretrial disclosure, or failed to serve a bill of particulars as to their fourth affirmative defense, under circumstances that would warrant either the extreme sanction of striking their fourth affirmative defense or precluding them from offering evidence in support of that defense (see CPLR 3126; cf. Kihl v. Pfeffer, 94 N.Y.2d 118).

For the foregoing reasons, the Supreme Court should not have determined whether the injured plaintiff is covered by the Workers' Compensation Law, and should have instead deferred decision on the motion and cross motion pending a prompt application for benefits under that law, and resolution of that application (see Kayen v. Shames Realty, supra).
