Here's the quote from The Malaysian Insider:
Mohd Nizam: “Although the orders have been confirmed by the Sultan. If the decision is ultra vires then the decision can be adjudicated by the court.”
Jagdeep then asked Nizam to explain what ultra vires means to the court.
Nizam looking confused and replied: “To insult.”
Jagdeep then told Mohd Nizam that his misunderstanding of the word had caused chaos in the country because the word actually means “beyond the powers”.
