Police evidence crucial to the defence case of 22-year-old Shannon Wylie still has not been handed over despite a specific request on the last occasion, the court heard.

Wylie remains behind bars on 27 separate drug charges and five for the alleged sexual assault of a 14-year-old girl.

"At least provide a partial brief so that our learned friend does not have to wade through a large number of documents quickly," Magistrate Michael Holmes said.

"Just serve a partial brief as soon as possible."

Shannon Wylie's case has been adjourned until June, while co-accused Sterling Wylie, James Faulkner and Eloise Hemsley also had their cases adjourned until June and July in Armidale Local Court on Wednesday. Co-accused Alice Snyder was not listed on the same day.

The accused were arrested as part of Strike Force Janian which saw police storm three properties in Armidale on December 21.

Eloise Hemsley, 20, was the latest to be charged in the operation facing one count of taking part in the supply of more than a commercial quantity of MDMA.

Strike Force Janian was one of the largest police drug bust operations by New England and Coffs Harbour officers and spanned 16 months.

In a series of dawn raids in December, police searched three homes in Armidale as well as a nearby business and another home in Uralla. Ecstasy pills, MDMA, cocaine and cash were seized.
