§ 625. Undertaking on appeal. No appeal shall be taken by an employer
from a decision of the appeal board determining a sum to be due from
such employer unless the amount involved, with interest and penalties
thereon, if any, shall be first deposited with the commissioner and an
undertaking filed with the commissioner, in such amount and with such
sureties as a justice of the supreme court shall approve, to the effect
that the employer will pay all costs and charges which may be adjudged
against him in the prosecution of such appeal. At the option of the
employer, such undertaking may be in a sum sufficient to cover the said
amount, interest, penalties, costs, and charges as aforesaid, in which
event the employer shall not be required to deposit such amount, with
the interest and penalties, as a condition precedent to the taking of an
appeal.
