A British High Court judge is to hand down his judgment on a demand for "punitive" damages against Robbie Williams.
It comes in the wake of a court ruling that one of the tracks on his second album contained "substantial" copying from an earlier lyric.
In October 2000, the British High Court held that the song Jesus in a Camper Van was a breach of copyright.
The song, co-written with Guy Chambers for the album I've Been Expecting You, was said to be a breach of copyright in Woodie Guthrie's I Am The Way, and in an adaptation of the song by Loudon Wainwright III.
Mr Justice Pumphrey is giving his ruling on the amount of compensation to be awarded to the copyright holders, New York-based Ludlow Music, against Williams, Chambers, and the singer's record and publishing companies.
The judge has heard claims that Ludlow had been willing from the outset of the dispute to grant a licence on condition that it received 50% of the royalties from the Williams song.
But the defendants, who offered no more than 25%, went ahead and sanctioned release of the recording on the Chrysalis label without Ludlow's authority.
