Phil Spector Sues from Inside Prison -- My House Is Being Murdered

Phil Spector just filed a lawsuit from BEHIND BARS -- claiming the house where he murdered actress Lana Clarkson in 2003 is being destroyed by a local government construction project ... and now, he's suing.

Phil and his wife filed the lawsuit today in L.A. County Superior Court against the City of Alhambra -- where his wife currently resides ... while Phil rots away in prison.

According to the lawsuit, the city commissioned a construction project on the hill where Phil's house is located -- a project that has since caused the retaining wall that supports the hill to start cracking.

As a result of the cracked wall, Phil claims there have been landslides and land-sinking problems -- causing significant damage to his house.

Phil is suing for unspecified damages to cover the massive repair costs -- as well as compensation for loss of property value.

Back in 2009, Phil was convicted of shooting Lana Clarkson in the foyer of the house ... even though he was adamant Clarkson shot herself. He's currently serving a sentence of 19 years to life.

We called the City of Alhambra for comment -- so far, no response.
