Thicke and Williams were ordered to hand over $7.4 million (GBP4.9 million) to Gaye's kids in court on Tuesday (10Mar15), but their lawyer, Howard King, has revealed the songwriters plan to appeal or seek a retrial if the judge overseeing the case denies a motion requesting the verdict be set aside.

King insists his clients maintain Blurred Lines was an original song created solely by them, and he claims jurors may have been convinced otherwise by expert testimony which should have been inadmissible in court.

The attorney says, "Based upon their own feelings that they created Blurred Lines from their own hearts and souls and no one else, and based on feedback from other prominent songwriters, they (Thicke and Williams) feel they owe it to the creative world to make sure this verdict does not stand."

Meanwhile, the Gaye family's lawyer, Richard Busch, is seeking a court injunction against further distribution of Blurred Lines based on Tuesday's verdict.
