In this online multiple choice question, I picked the last choice. I agree that the first choice is true, but why's the last one wrong?
Why can't a public body exercise its powers for any purpose allowed by the empowering statute?
The posted answer has it, I think. It’s a question about statutory interpretation requiring multiple choice answer interpretation! Like, imagine a friend gives you their credit card and asks you to pick them up something from the store. There’s no reason for you to think that because you are allowed to go buy item X, you’re also allowed to go buy items Y and Z. Finally, a good rule of thumb for questions like this, where you just don’t know if it could be between two... an answer that contains always, never, every, etc is almost certainly the wrong one. Never be so certain!– A.fm.Feb 15, 2021 at 21:12
Break it down then take it to an absurd extreme to prove a point:
HMRC exercises its powers to collect PAYE tax
For the purposes to fund the NHS and to pay for all its employees to have a free hair cut once the current lockdown has been lifted
One of which is allowed by statute (PAYE not hair cuts)
The free hair cuts might be a public health measure to combat Cholera, Typhoid fever and other 1900 "contagious diseases"– TrishFeb 15, 2021 at 13:44
I'm thinking more about the here-and-now. I last had my haircut in 2019 BC (that's Before Covid) and I'm starting to look like it's the 70's all over again - if you weren't around then it was an eclectic mix of Farrah Flicks, mullets and mohecans.– RickMar 31, 2021 at 0:20
