Gubis invoices related to ad hoc services needed to be signed by Director Malatji because the executive instructed deployment and payment must come from the Watchman services vote, which falls under Malatji's responsibility.
“Gubis was instructed by the Department of Water and Sanitation ... such invoices were supposed to be signed by me ... by virtue of the executive having instructed the deployment thereof ... those invoices had to be paid from my vote, the Watchman Services.”
