He was accused of leaving a harsh comment under a post on Odnoklassniki in September 2020, which criticized Alexander Lukashenko and posted it on his own page. District Court Judge Shamal found him guilty of insulting Lukashenko (Part 2, Article 368 of the Criminal Code of the Republic of Belarus) and defamation (Part 2, Article 367 of the Criminal Code of the Republic of Belarus). He appealed the verdict to the Mogilev Regional Court. The appeal took place on April 11, 2024, behind closed doors, with the participation of a panel of judges chaired by Judge Irina Teplova. The regional court ruled that the charge of "insulting Lukashenko" under Part 2, Article 368 of the Criminal Code, was excessively imputed and should be excluded from the charges.
According to calculations, he was supposed to be released in the spring of 2026 .
However, this had little effect: Sergei Shekh's sentence was upheld.
