1506 LAWS OF MARYLAND. [CH. 714

may be exercised only by the Commission or the respective
boards of zoning appeals created or authorized by this Act.

Insofar as the provisions of said Chapter 599 of the Laws
of Maryland, 1933, may be inconsistent with or contrary to
the provisions of this Act, such provisions of the Act of 1933
shall have no application within the District.

SEC. 31. And be it further enacted, That no clerk of the
Circuit Court of Montgomery County or of Prince George's
County, no administrative official, no licensing body or board
nor any person whatever shall issue a license or permit for
any commercial or industrial purpose or for the conducting
of any commercial or industrial enterprise or business what-
soever in a residential zone, that is, in any district designated
on the zone maps as residential within the District. Provided,
however, that in the case of a lawful non-conforming use ex-
isting at the time of the enactment of the respective zoning
ordinances within that portion of the District in Montgomery
and Prince George's Counties, comprising the Maryland-Wash-
ington Metropolitan District, created by Chapter 448 of the
Laws of Maryland of 1927, as amended, the particular use may
be continued and appropriate licenses be issued, limited, how-
ever, to the particular use already existing in each case; and
provided further, that the Liquor Control Board of Mont-
gomery County may, within its discretion, renew such licenses
as were lawfully renewed by it in 1938 for premises on which
lawful non-conforming uses either as restaurants, grocery
stores, or roadside stands have continuously existed since 1928;
and provided further, that in the case of a lawful non-con-
forming use existing at the time of the enactment of zoning
ordinances under the provisions of this Act in that portion of
the District in Montgomery and Prince George's Counties, re-
spectively, outside the Maryland-Washington Metropolitan
District, the particular use which may exist at the effective
date of the said zoning ordinances, adopted under the author-
ity of this Act, may be continued and appropriate licenses be
issued, limited, however, to such particular use in each case.
For the purpose of carrying out the provisions of this section,
the Commission shall supply every such Clerk, administra-
tive official, licensing body or board, and every other official
or body empowered to issue any license or permit, with a
copy of the map or maps showing the residential, commer-
cial, industrial and other zones or districts in the District.
Every license or permit issued in violation of this section
shall be invalid; and the issuance of any such license or permit
is hereby declared a misdemeanor and punishable as other
misdemeanors are punishable under Section 27 of this Act.
