183. The Commissioner of Motor Vehicles is hereby authorized and
directed to refuse to issue or transfer any plate or marker, certificate of
registration or title for any motor vehicle unless all taxes due and in ar-
rears on the motor vehicle described in the certificate of registration or
title so to be issued or transferred have been paid provided each motor
vehicle is separately assessed apart from the assessment on any other motor
vehicle or kind or class of assessable property and provided the tax to be
levied on such motor vehicle is permitted except in Baltimore City to be-
paid separate and apart from the payment of all other taxes. And it shall
be mandatory upon the County Commissioners to provide for separate-
assessments and separate tax bills. This section shall apply only in the
case of taxes becoming due and in arrears the year 1924 and thereafter,
upon motor vehicles owned in the City of Baltimore, and in the case of
taxes becoming due and in arrears in the year 1927 and thereafter, upon

Unless otherwise permitted by statute, whole amount due for any single tax
must be paid or tendered; mandamus refused to compel city collector to accept
anything less than amount of taxes due and in arrears for any one year. Balti-
more v. Fine, 148 Md. 325.

ence to it in the title or the enacting clause, but it is identical in form to said section
as amended by ch. 707 of acts of 1927.
