Wisconsin High School Student concern. My son is on a School Trip to France. He is 18 and legal to drink there. He was caught drinking alcohol and because he was on a school sponsored trip they said he will be receiving an under age drinking ticket when he gets back to Wisconsin. The rules of the program warn that there can be no illegal substances, but he is the only one 18 years old and legally can drink in the country. The program also states he is bound by the laws of that country. Is it legal for the school to obtain City citations for underage drinking for him back in Wisconsin?
