A trainee care worker was fined for parking illegally after pulling over to help a 91-year-old woman who had collapsed in the street.
Christopher Bone appealed against the fine following the incident in June, but Waltham Forest Council insist the penalty must stand.
The father-of-two, of Edward Road in Walthamstow, was driving in Markhouse Road when he saw the woman fall to the ground.
He pulled over and parked leaving two wheels on the curb to allow traffic to pass, leaving his children and partner in the car.
Mr Bone, an apprentice at George Mason Lodge in Chelmsford Road, Leytonstone, is qualified in first aid and phoned an ambulance as he treated the woman's head wound until paramedics arrived.
He said: "I stopped the car without a thought. What was I supposed to do, just drive on when she could possibly have died or had a heart attack?
"I gave her medical attention as that is what I'm trained to do. When I asked her what happened, she said her legs 'just gave way', so I didn't feel safe leaving her before the ambulance arrived."
As he treated the woman, Mr Bone said he spotted a CCTV spy car drive past slowly and the driver look at him with the elderly lady.
It then indicated to stop further up the road from his black Ford Focus.
Minutes later, a van driver shouted out to Mr Bone that he was getting a ticket, so he moved his car into a nearby residential street.
A week later Mr Bone received the £65 parking fine and appealed within 48 hours, providing evidence including the ambulance CAD number.
He has also sent the council a letter from the London Ambulance Service detailing his actions on the day.
But the council refused to withdraw the penalty.
Mr Bone says he asked the council what course of action he should have taken to help the injured lady, but has not received a response.
He added: "[parking enforcement officers] are in a position of power and could have at least asked what was going on before giving me a fine and then buggering off.
"I believe they're acting in a disgusting, money-grabbing way with no compassion.
"I've given the council all the evidence they've asked for, it should be over-turned,"
Mr Bone has until tomorrow to pay the original fine £65, or it will be doubled.
The council has been asked to respond.
