The analytical study entitled "The Constitutional Limits of Executive Power under a State of Emergency in Palestinian Legislation" addressed the most prominent constitutional issues arising from exceptional circumstances, namely the question of the adequacy of constitutional provisions to limit the overreach of executive power and safeguard rights and freedoms during times of crisis. Through its comparative analytical approach, the research concluded with a set of legislative and practical realities. Firstly, it affirmed that the amended Palestinian Basic Law of 2003 adopted a restrictive approach to exceptional legitimacy, prohibiting any infringement upon inherent human rights and dignity, thus establishing the principle that freedom is the norm and restriction the exception. However, the research revealed a highly complex constitutional gap: the constitutional legislator's failure to regulate the "legal extension" of exceptional circumstances after the expiration of the thirty-day period stipulated for declaring a state of emergency. This led, in the absence and dissolution of the Legislative Council, to the executive authority resorting to the unprecedented practice of automatic and successive extensions through separate decrees to ensure the continuity of public services and address evolving risks such as the COVID-19 pandemic.............
