The authorities are multiplying the legal provisions enabling them to free themselves from the rule of law: arbitrary extension of police custody, prohibition of meetings and rallies, submission of publications to prior censorship, restriction of freedom of movement through the establishment of passes or curfews, prohibition for trade unions to issue subscriptions, etc. Anyone accused of "compromising public safety" is deprived of a lawyer and cannot appeal the judgment. Sentences of life imprisonment at hard labour or death penalty – executions can be public – are thus numerous. A one-party system was introduced in 1966.
