It's not true. They're talking about a law from 1958 (under a conservative president, like almost all of them until 1981) that makes it illegal to criticise a court decision in order to undermine the legitimacy of justice.
It's okay to criticise a court decision if you just don't agree with it, but not to say "see this judgments? it shows all judges are corrupted".
