Howard K. Stern had a very good reason for having a big grin painted on his face as he left a Los Angeles County courthouse earlier today. The attorney was acquitted acquitted of all charges in the Anna Nicole Smith drug conspiracy case.

Look below for the details:

Back in October, Stern (Anna Nicole’s former domestic partner) was found guilty of conspiracy in using false names to fuel Smith’s drug addiction. But today, the judge over the case, citing a lack of evidence, felt as though the jury’s conviction was baseless and dismissed their guilty verdict.

“We strongly disagree with Judge Robert Perry’s ruling today,” District Attorney Steve Cooley said, adding, “[the ruling] diminishes the huge social problem of prescription drug abuse facilitated by irresponsible caretakers and unscrupulous medical professionals.”

Cooley also tells TMZ that he has plans to appeal the ruling.
