Failure to file such notice within the time provided, may be excused if it can be shown not to have been reasonably possible to furnish such notice and that such notice was furnished as soon as possible. On demand the employer or carrier shall forthwith deliver to the board the original or a true copy of the health care provider's report, wage and employment data and all other documentation in the possession of the employer or carrier with respect to such claim.
The chair or designee, shall have full power and authority to determine all issues in relation to every such claim for disability benefits required or provided under this article, and shall file its decision in the office of the chairman. Upon such filing, the chairman shall send to the parties a copy of the decision. Either party may present evidence and be represented by counsel at any hearing on such claim. The decision of the board shall be final as to all questions of fact and, except as provided in section twenty-three of this chapter, as to all questions of law. Every decision shall be complied with in accordance with its terms within ten days thereafter except as permitted by law upon the filing of a request for review, and any payments due under such decision shall draw simple interest from thirty days after the making thereof at the rate provided in section five thousand four of the civil practice law and rules. The chair shall adopt rules and regulations to carry out the provisions of this article including but not limited to resolution of contested claims and requests for review thereof, and payment of costs for resolution of disputed claims by carriers.
