Wendy Lees, who lives at Lynton, Rue des Marettes, has been trying to have the 17-metre trees reduced in size because she says that they substantially cut out light to her garden and house.
Planning were in support of her case and ordered that her neighbours, Michael and Pamela Brimacombe, trim six 100-year-old oak trees down to seven metres and maintaining them at a height of not more than eight metres.

On Thursday, both parties attended the Royal Court to battle it out. Judgment was reserved
