I'm not sure I understand your question, but the dictator would be the onewho decides what is and isn't acceptable, and it's a trait of dictators that they don't pay much attention to checks and balances. Of course, any dictator worth their salt will immediately ban any expression of discontent with said dictatorship. Similar to how in Thailand it's an offense to criticise the monarchy.
