In what has been a multi-year battle, U2 guitarist the Edge's proposal to build a series of Mansions on his Malibu has been denied by the California Coastal Commission.

The Edge, who co-owns a 136-acre plot in Malibu, has been trying to build five mansions on the property since 2006. He has argued that the development would be environmentally friendly, but opponents claim that the buildings would disturb the natural vegetation and ruin coastal views.

A representative for the Edge and his fellow property owners released a statement condemning the California Coastal Commission's decision, which voted 8-4 to reject the U2 rocker's plan. "They undertook this effort with a deep personal commitment and sense of responsibility to protect environmental resources and develop environmentally superior homes," said the rep, Fiona Hutton, in a statement.

There's now a very likely chance that the matter will be settled in court, as Hutton says a lawsuit by the Edge and his real-estate partners is a "strong option."
