The man doing business with Katherine Jackson wants a lawsuit tossed out of court because, he claims, the King of Pop did not invent 'The Smooth Criminal' lean -- the world famous anti-gravity dance move.

EXCLUSIVE DOCUMENTS: 'The Smooth Criminal' Legal Papers

"That 'lean' pose in question was NOT invented by, or first introduced to audiences by, Michael Jackson," lawyers for Howard Mann state in court documents, obtained exclusively by RadarOnline.com.

Katherine Jackson was persuaded by her son, Randy, to file the wrongful death lawsuit against AEG, RadarOnline.com has exclusively learned.

“Katherine didn't want to sue AEG for Michael's death,” a source with knowledge of the situation tells us.

“Katherine was ultimately swayed by her son Randy to sue AEG.

“Most people assume that the lawsuit was Joe's -- and that Joe controls Katherine, but Randy has much more control of Katherine than Joe does.

The wrongful death lawsuit that Katherine filed against AEG stunned even her closest advisers who weren't notified about the action.

“Katherine has a couple of business associates that are independent of any Jackson family control or influence,” said the source.

“Those associates weren't told about the lawsuit and were absolutely stunned, as they had advised her in the past not to sue AEG.”

Michael's three children, who live at the Jackson family Encino compound, are going to have to endure their dad's name being dragged through the mud again, the source claimed.

“Michael's children are going to suffer the most because of this lawsuit,” added the source.

“It's truly sad that they are going to have to go through this. The kids will hear unflattering things about their dad because of this lawsuit.
