Translate the following English sentence to French:
"There is nothing to indicate that the Member States' legal principles, legal traditions and carefully tailored legal systems should be lost for reasons to do with an already familiar offence such as counterfeiting. Nor, in the light of the international convention of 20 April 1929, can there be any confusion as to which country should deal with any criminal cases."
Conformément à la convention internationale du 20 avril 1929, il ne peut non plus y avoir de confusion quant à savoir quel pays doit examiner une éventuelle affaire pénale.
