Mr Boggis has spent a fortune on his fight to overturn a decision by Natural England
A High Court judge hearing the case of a retired engineer fighting to protect his Suffolk home from coastal erosion has reserved judgement in the case.
Natural England wants fossil-bearing cliffs near Southwold to be allowed to wear away, raising the prospect that some homes could fall into the sea.
But Peter Boggis, 77, has installed his own defences near his Easton Bavents home and is fighting to maintain them.
Mr Justice Blair is expected to give a his ruling before Christmas.
Natural England declared the area a Site of Special Scientific Interest (SSSI) in 2006, with the intention of preventing Mr Boggis from maintaining his sea defence barrier.
Mr Boggis has argued that Natural England had no legal right to stop him saving his home.
The court case has now finished and the judgement will be made at a later date.
