2068                                Laws of Maryland

Maryland employer of an employee or employees regularly employed
by said employer within this State shall be construed to be employ-
ment within this State; provided, however, if an employee or the
dependents of an employee shall receive compensation or damages
under the laws of any other state, nothing herein contained shall be
construed so as to permit a total compensation for the same injury
greater than is provided for in this article.

An employee and his employer who are not residents of this
State and whose contract of hire is entered into in another state
shall be exempted from the provisions of this article while such
employee is temporarily or intermittently within this State doing
work for such nonresident employer, if such employer has furnished
workmen's compensation insurance coverage under the workmen's
compensation or similar laws of such other state, so as to cover such
employee's employment while in this State; provided the extra-
territorial provisions of this article are recognized in such other
state and provided employers and employees who are covered in
this State are likewise exempted from the application of the work-
men's compensation or similar laws of such other state. The benefits
under the workmen's compensation act or similar laws of such other
state shall be the exclusive remedy against such employer for any
injury, whether resulting in death or not, received by such employee
while working for such employer in this State.

A certificate from the duly authorized officer of the industrial acci-
dent commission or similar department of another state certifying
that the employer of such other state is insured therein and has pro-
vided extraterritorial coverage insuring his employees while working
within this State shall be prima facie evidence that such employer
carries such compensation insurance.

31.

Any employer, his employee or employees engaged in works not
[extra-hazardous] within the meaning of this article, may by their
joint election, filed with the Commission, accept the provision of this
article and such acceptances when approved by the Commission, shall
subject them to the provisions of this article to all intents and pur-
poses as if they had been originally included in its terms.

Any workman of the age of sixteen years and upwards may him-
self exercise the election hereby authorized. The right of election
hereby authorized shall be exercised on behalf of any workman under
the age of sixteen years by his parent or guardian.

The provisions of this article shall apply to employers and em-
ployees engaged in intrastate and also in interstate or foreign com-
merce, for whom a rule of liability or method of compensation has
been or may be established by the Congress of the United States,
only to the extent that their mutual connection with intrastate work
may and shall be clearly separable and distinguishable from inter-
state or foreign commerce, except that any such employer and any
of his workmen only in this State may, with the approval of the
Commission, and so far as not forbidden by any act of Congress,
voluntarily accept the provisions of this article by filing written
acceptance with the Commission, which shall subject the acceptors
to the provisions of this article to all intents and purposes as if they
had been originally included in its terms.
