In this workers’ compensation case, claimant seeks review of an order by the Workers’ Compensation Board dismissing employer’s request for review. The issue is whether the Board retains jurisdiction to review a referee’s order when the requesting party withdraws its request to review, after the responding party, without filing a timely cross-request, questions the validity of the referee’s order.

Claimant’s husband died on May 29,1985, from ventricular fibrillation, which was a result of his compensable condition. On June 20, 1986, a referee awarded 100 percent unscheduled permanent partial disability and costs of medical services on the deceased husband’s claim but denied her widow’s benefits.

Employer timely requested review of the order. On October 1, 1986, after the time for cross-request had expired, claimant filed a brief in which she raised the issue of her eligibility to receive widow’s benefits. Employer then withdrew its request and moved for dismissal. The Board granted the motion, and claimant appeals.

She relies on Neely v. SAIF, 43 Or App 319, 602 P2d 1101 (1979), rev den 288 Or 493 (1980), which holds that a party need not cross-petition for review and that the Board may reach on de novo review an issue first raised in briefs before it. Employer contends that, by withdrawal of the request for review, the Board was deprived of its jurisdiction to review, and the case was properly dismissed. It relies on R.A. Gray & Company v. McKenzie, 57 Or App 426, 645 P2d 30, rev den 293 Or 340 (1982), which holds that a respondent who has not cross-appealed cannot recover a more favorable judgment from the appellate court than it had below.

Claimant is correct that the Board can reach issues raised by a responding party on de novo review without a formal cross-petition. Neely v. SAIF, supra, 43 Or App at 323. The essential prerequisite of the Board’s review power is, however, that it have jurisdiction. Here, the Board acquired jurisdiction when employer filed its request for review. ORS 656.295. It lost it when employer withdrew the request. Although claimant questioned the denial of widow’s benefits in her brief to the Board, the brief was filed after the statutory *428period for a request for review, ORS 656.289(3),1 and thus it could not be considered or treated as a timely cross-request. In Neely, the Board retained jurisdiction of the request for review and could review issues raised by the responding party. Here, when employer withdrew its request, the Board was deprived of jurisdiction and properly dismissed the case.

Affirmed.
