Judge John Cleland denied the motion after Sandusky lawyer Joe Amendola filed a 20-page response that described and defended the demands for information he has issued to police, schools and other institutions in preparation for next month's trial.
A hearing has been scheduled for next week on the topic.
Amendola also filed a "motion to compel" that asked Cleland to order the release of prosecution materials "forthwith," and Cleland promptly directed the attorney general's office to provide materials that are not in dispute before the Wednesday hearing, and to tell him in writing by the end of the day Monday if there are any remaining conflicts.
Sandusky, 68, is charged with the sexual abuse of 10 boys over 15 years. His trial is scheduled to begin June 5. Sandusky has repeatedly denied the prosecution's charges.
