notice an opportunity for fair hearing in accordance with the
provisions of this section with respect to hearings and deter-
minations on appeal. The parties shall be promptly notified
of the determination, together with the reasons therefor in
the event of denial of the claim, and such determination shall
be deemed to be the final decision on the claim, unless within
seven days after the mailing of notice to a party's last known
address, or, in the absence of such mailing, within seven days
after the delivery of such notice, appeal is taken to the Board
or notice of review is entered by that body.

(d) Notice of Determination. Notice of a determination
upon a claim shall be promptly given to the claimant by de-
livery thereof or by mailing such notice to his last known
address. In addition, notice of any determination which in-
volves the application of the provisions of Section 5 or Sub-
section (c) of Section 4 of this Act, together with the reasons
therefor, shall be promptly given in the same manner to the
last employing unit by whom claimant was employed; provided
that the Board may dispense with the giving of notice of any
determination to any employing unit and such employing unit
shall not be entitled to such notice if it has failed to indicate
prior to the determination, as required by regulation of the
Board, that the claimant may be ineligible or disqualified
under any provision of this Act.

(e) Appeal to Referee. The claimant or any other party
entitled to notice of a determination as herein provided, may
file an appeal from such determination with the Board within
seven days after the date of mailing of the notice to his last
known address or if such notice is not mailed, within seven
days after the date of delivery of such notice.

Unless the appeal is withdrawn or is removed to the Board,
a referee designated by the Board, after affording the parties
reasonable opportunity for a fair hearing, shall make findings
and conclusions and on the basis thereof affirm, modify, or
reverse such determination; provided, however, that whenever
an appeal involves a question as to whether services were per-
formed by claimant in employment or for an employer, the
referee shall give special notice of such issue and of the pen-
dency of the appeal to the employing unit and to the Board,
both of whom shall thenceforth be parties to the proceeding
and be afforded a reasonable opportunity to adduce evidence
bearing on such question.

The parties shall be promptly notified of the referee's deci-
sion and shall be furnished with a copy of the decision and the
findings and conclusions in support thereof and such decision
shall be final unless, within seven days after the date of mail-
ing of notice thereof to the party's last known address, or in
