If a public dance hall permit has been issued under the provisions of this chapter,
and such public dance hall is being conducted in violation of the laws of this state
or of this chapter, or of any other law or ordinance relating to the operation of
public dance halls, the director of police services may at any time give notice in
writing to the holder of the permit or other person in control of the operation and
maintenance of such public dance hall that the permit has been revoked and cancelled.
Such written notice shall state the reason for such revocation and cancellation and
shall become a final revocation and cancellation after the expiration of ten days
from the date of service of such notice, unless on or before the expiration of such
ten days the permit holder or other person in control of the operation and maintenance
of the public dance hall shall file with the director of police services a written
request for a hearing before him or her upon the question whether or not the permit
should have been revoked and cancelled. Such hearing shall be held by the director
or his or her designated representative within 30 days after the date of the filing
of such request therefor, and the action and judgment of the director of police services,
after hearing all the evidence and facts, shall be final and subject to court reviews
as provided by law.
