Since President Putin is an official the punishment can be:
1. a fine of 5000-10000 roubles,
2. a fine up to the person's monthly income,
3. compulsory(?) labour of 120-180 hours, (A person is made to perform a community job in his/her free time)
4. correctional labour up to 6 months (the government confiscates 5-20% of a convicts' income).
Article 319 of the Russian criminal Code.
