Practice Relating to Rule 55. Access for Humanitarian Relief to Civilians in Need
Section B. Impediment of humanitarian relief
In its judgment in the Albasyouni case in 2008, concerning a petition regarding the Israeli Government’s decision to reduce or limit the supply of fuel and electricity to the Gaza Strip, Israel’s High Court of Justice stated:
14. The State’s arguments are based on norms of international customary law, which specifies the basic obligations applying to parties engaged in an armed conflict, and requires the parties to ensure the wellbeing of the civilian population and protect its dignity and fundamental rights. It would not be superfluous to add that, under customary international humanitarian law, every party to the conflict must refrain from impeding the passage of basic humanitarian relief to the population requiring such in areas under the control of that party to the conflict …
15. The above indicates, therefore, that the Respondents do not disagree that they are bound by the humanitarian obligations imposed upon them, which require the State of Israel to allow passage of vital humanitarian goods to the Gaza Strip …
22. … [T]he State of Israel is required to act against the terrorist organizations within the framework of the law and in accordance with the dictates of international law, and to refrain from deliberately harming the civilian population located in the Gaza Strip. 
Israel, High Court of Justice, Albasyouni case, Judgment, 30 January 2008, §§ 14, 15 and 22.
