2:43 PM PT -- A rep for State Farm tells TMZ that Shannen's latest motion "once again distorts the facts. Rather than try this smoke damage case in the media, we will do so in a court of law."
Shannen Dohertyclaims State Farm is engaging in a smear campaign against her, and exhibit A is a cheap shot it took about her tobacco use ... which she calls way over the line.
The former '90210' star filed new legal docs, obtained by TMZ, claiming State Farm is invading her privacy and making false claims about her smoking habits. As a result she wants a judge to punish the insurance giant with crippling sanctions.
Shannen says State Farm got it totally wrong when it claimed, in docs, she was smoking cigarettes up until March 2019. Total BS, according to Shannen, who says she kicked the habit back in 2015 ... after her original breast cancer diagnosis.
Of course, her recent stage 4 cancer diagnosis is at the center of her legal beef with State Farm. They're haggling over her home repair costs following the devastating California wildfires.
