The 7th Criminal Chamber of the Court of Appeals, in its judgment dated 11 February 2009 No. 2006/16811 E., 2009/2220 K., highlights the prominence of the principle of law "no crime or punishment without law" by abolishing the provisions of Decree-Law No. 556 that define crimes in relation to trademarks on the basis of the said principle. Thereby, this judgment creates a gap in the law due to the provisions of the Turkish Commercial Code (Law No. 6762) in relation to the crime of unfair competition formerly repealed upon the coming into effect of the previously abolished regulation on trademarks.
