A MAN accused of taking fudge brownies laced with cannabis to TAFE has told a court he picked up the wrong lunchbox.

David Lance Blythe, 32, of North Hobart, appeared in the Hobart Magistrates Court today charged with possessing a controlled plant, using a controlled plant and supplying a controlled plant.

The charges relate to an incident on a TasTAFE campus in Hobart in June last year.

Several other students allegedly consumed some of the brownies.

The case was listed for hearing yesterday but Prosecutor Liz Avery told the court that while prosecution had statements from two students, it was still seeking a third and was waiting for a statement from an interstate pathologist.

Chief Magistrate Michael Brett said the delays in getting the case to trial were indefensible and allowed an adjournment for Mr Blythe to show the continued delays were amounted to an injustice.

The defendant said it was the second time he’d attended court expecting a hearing in the last five months and accused the prosecution of “stalling tactics”.

He protested his innocence to the court.

“I told the judge that I was not aware there was cannabis in the fudge brownies, someone else made the fudge brownies and I took the wrong container,” he said.

He also claimed that blood tests of those who allegedly consumed the brownies had not been carried out in a timely fashion.

Mr Blythe said the delays in the case were affecting his chances of maintaining his employment and were causing him to become depressed.

The case returns to court next Thursday.
