In People v. Malmud, 4 A.D.2d 86 (2d Dept. 1957) the Second Department upheld the defendant's conviction for violating a regulation of the Authority, and found that the power to promulgate that regulation was solidly based on "the power granted to the Authority by clear implication to adopt rules regulating traffic on it projects, ... subject to the condition, just as clearly implied, that it may adopt only such rules as upon reasonable grounds it may deem necessary and proper to provide for the safety and convenience of those who use them, and the protection of its facilities from unwarranted damage."
