Prohibition of advertising games of chance permitted if other Member State does not provide equivalent protection of gamblers
"37. [...] Article 56 TFEU must be interpreted as not precluding legislation of a Member State which permits the advertising in that State of casinos located in another Member State only where the legal provisions for the protection of gamblers adopted in that other Member State provide guarantees that are in essence equivalent to those of the corresponding legal provisions in force in the first Member State."
