Dr Nunn and husband Geoff have taken their case to the Appeal Court

Christine Nunn, 45, of Bardsey, Leeds, tries to avoid using her mobile "more than necessary", her counsel said.

Her lawyers are asking judges to rule that her European rights to an independent hearing have been breached.

The mast was allowed after Leeds City Council was one day late in dealing with objections to the scheme.

Fortunate

Counsel David Wolfe told the Court of Appeal in London that Dr Nunn and her family, who also suffer migraines, moved to the house because they believed it was in an area where there were "no aggravating factors".

"They considered themselves fortunate to find such a home."

But the mast was built close to the house and objections from Dr Nunn and other residents had so far failed to get it removed.

Mother-of-three Dr Nunn and her neighbours objected at a local inquiry that, health implications aside, the structure would reduce property values and have an adverse impact on local amenities.

But the inquiry inspector said he could not deal with their objections because the city council had failed to lodge a notice of objection with T-Mobile within a statutory 56-day deadline.

The council put in the notice a day late, believing it was still within the time limit.

The inspector ruled that T-Mobile was deemed to have permission under current planning legislation and quashed an enforcement notice issued by the council.

Last year that decision was upheld in the High Court.

T-Mobile says there is no substantial evidence to support the claims of health risks relating to emissions from mobile phone base stations.

It also says there is no evidence of "direct and serious interference with amenity."

The hearing is expected to last for two days.
