The Solicitor-General is appealing against the home detention sentence given to a man who mugged an 81-year-old woman.
Darren Fidow was 18 in 2011 when he attacked and robbed Pat Sutcliffe at an Auckland shopping centre, breaking her hip.
He was sentenced to nine months' home detention - a sentence the Crown says was manifestly inadequate and wrong in principle.
Mrs Sutcliffe says she has a limp for the rest of her life and a jail sentence would be a fairer reflection of her attacker's crime.
"There was nothing wrong with me before," she says. "I could get round the same as a 20-year-old. He's disabled me from what I can do. With every step I take I feel that side of me, that hip - and that's not going to change."
No date has been set for the Court of Appeal hearing.
