Dismissals described as 'affront' to judicial independence
Regional director of the International Commission of Jurists, Said Bernabia, slammed the dismissals in a series of tweets. "The amendment is an affront to the separation of powers and judicial independence. Through it, the collapse of the rule of law the constitutional order is now complete," Bernabia said.
The president has been accused of increasing his grip on power since last year's suspension of the country's parliament, the dismissal of the sitting prime minister and granting himself executive powers.
Saied has in the past said that the measures he has taken are intended to save Tunisia from collapse.
However, critics say he is leading the country firmly on the path toward authoritarian rule.
