The judge in the sexual exploitation trial of former sports agent David Frost has ruled he will not shield the names of several women expected to take the stand as witnesses, women who were teenagers when the alleged offences took place.

Justice Geoff Griffin said he knows that will result in humiliation for the women, but he could find no legal reason to have their identities protected.

Griffin also ruled he will accept the majority of Crown evidence that the defence had argued is irrelevant.

Frost coached the Quinte Hawks in the 1990s, when the offences were alleged to have taken place. He is charged with four counts of sexual exploitation.

On Wednesday, prosecutors said they would paint Frost as someone who controlled the lives of his players so thoroughly that he could order the teens to participate with him in sexual acts.

Lawyers acting for Frost said their client would deny the acts ever took place.
