Britain's longest serving huntsman went to the High Court yesterday claiming the ban on hunting with hounds infringed his human rights.
Roger Bigland, a terrier man with the North Cotswold Hunt, said he would lose his livelihood if the Government ban was not overturned.
The 61-year-old, from Evesham, Worcestershire, who has been hunting for 41 years, said he would eventually lose his job and home as a result of the ban, which came into force in February.
Mr Bigland is one of ten claimants who have taken their case to the High Court under the Human Rights Act. The others include a hare coursing trainer, a landowner, a dairy farmer and livery yard owner.
If the court agrees there has been a breach of human rights it can grant a declaration of incompatibility.
This would not overturn a ban on hunting but the Government would face considerable moral and political pressure to take action.
Mr Bigland said: "I have been doing this job for 41 years and it has been my life and my income.
"I will be 62 in the autumn and I am coming up for retirement and I don't want to start training to do something else. I have done nothing other than work in the countryside."
As a terrier man, Mr Bigland liaises with farmers and the hunt to find out where foxes may be causing problems.
Before a ban was implemented, Mr Bigland would "prepare" the countryside for a hunt, blocking off foxes' dens and repairing any damage caused as a result of the meet.
He fears a ban will lead to a complete eradication of foxes in the countryside, as farmers will choose to shoot them rather than let the local hunt control and maintain a healthy population.
"In this part of the world we are not a fox destruction society, but we are maintaining a sensible fox population that the countryside can tolerate.
"If we are taken out of the equation and if fox hunts don't continue, we are going to see the fox population completely annihilated because there will be people who will go out and shoot them all."
Mr Bigland said he had been guaranteed work for another 12 months as the North Cotswold Hunt, along with many others across the country, waits to see whether the Hunting Act can be overturned.
Hunts can continue carrying out pest control provided they only use two hounds to flush out a fox before it is shot. Some hunts said they would continue meeting to exercise hounds or begin 'trail' hunting, where a few hounds will follow a false scent.
"There will have to be a lot of hounds destroyed because if we continue in pest control we won't need the same amount.
"We have 40 hounds in kennels but we would only need ten. We wouldn't need so many horses and we probably only hunt twice a week instead of three times.
"There are four staff working for the hunt but three of us will go," Mr Bigland added.
