On February 10, 2022, Stanislau was detained, and the next day a court sentenced him to 15 days of administrative arrest. The reason was the number plate frames on his car decorated with an ornament and the Pahonia coat of arms. While Stanislau was serving the arrest, police officers found a photo from the protest of August 16, 2020, on his phone. He was not released when the arrest ended: Stanislau was detained again, this time in a criminal case, and placed in a pre-trial detention center.
In May 2022, Stanislau was found guilty in a criminal case initiated under the article "Organization and preparation of actions grossly violating public order, or active participation in them" for taking part in that protest and sentenced to restricted freedom without referral to an open-type correctional facility. He was released in the courtroom.
