The material process is most prominent (13 or 43.33%), emphasizing actions and events. The relational process follows (10 or 33.33%), highlighting relationships and attributes. Verbal and mental processes each account for 6.66% (2 verbal and 2 mental process) reflecting the importance of communication and cognition.

Adila Hassim's speech effectively combines these processes to present a strong and powerful argument for South Africa’s case against Israel at the ICJ.
