The ICJ's 24 January 2024 order was made before Israel's allegations against several UNRWA staff were made public on 25/26 January 2024 (I do not know if the allegations were privately made beforehand).
The ICJ's 24 January 2024 order does not mention the United Kingdom; it does not mention UNRWA in this context (it mentions UNRWA in the context of witness statements about the situation in Gaza).
Among other things, the order does say of Israel that:
- The State of Israel shall, pursuant to point (4) (c) above, in relation to Palestinians, desist from, and take all measures within its power including the rescinding of relevant orders, of restrictions and/or of prohibitions to prevent:
(a) the expulsion and forced displacement from their homes;
(b) the deprivation of:
(i) access to adequate food and water;
(ii) access to humanitarian assistance, including access to adequate fuel, shelter, clothes, hygiene and sanitation;
(iii) medical supplies and assistance; and
(c) the destruction of Palestinian life in Gaza.
However, it does not specify that the humanitarian assistance must be done via UNRWA.
For context, the UK, European Union, the USA, Canada, Australia, Finland, Germany, the Netherlands and Switzerland "suspended aid to UNRWA in response to reports [by Israel] that “several” UNRWA staff were involved in the 7 October Hamas assault against Israel". UNRWA is not the only mechanism of support, although "In every year from 2014 to 2022, at least half of UK aid to the West Bank and Gaza Strip has been delivered through the UNRWA, rather than through local authorities or civil society groups". Other countries, including Ireland and Norway, said they would not suspend their funding.
