Dr Eireann Kerr, whio now lives in Belfast, was convicted of committing the four offences inside Derry's Strand Road Police Headquarters following a Christmas works party night out with medical colleagues on 13 December, 2013.
Dr Eireann Kerr was convicted of the offences even though the court was told that there were traces of the date rape drug GHB in her system and that it was believed her drink had been spiked.
At yesterday's hearing, Dr Kerr's barrister Mr. Eoghain Devlin, said that representations they had made to the Prosecution Service had not been met with a satisfactory reply.
He asked for an adjournment of one week to explore 'whether there is an alternative avenue following the decision of the PPS.
Judge Philip Babington granted the request but said if the appeal was to proceed he wanted to deal with it before the summer break in early July.
The case will be mentioned again on June 15.
