Appeal court judges have been asked to delay challenges to the Lockerbie bomber's 27-year prison term.
Megrahi is appealing against his jail sentence for the bombing
Prosecution and defence teams have begun appeals in relation to Abdelbaset Ali Mohmed al-Megrahi's sentence.
Prosecutors have called for a longer sentence while al-Megrahi's team has been trying to get it reduced.
The Libyan's legal team has asked judges to put the challenges on hold until the Scottish Criminal Cases Review Commission looks at the case.
Judges were due to consider arrangements for the arguments from both sides in Edinburgh on Thursday and a hearing had been pencilled in for July.
However, defence QC Margaret Scott asked Lord Johnston, sitting with Lords Philip and Kingarth, to delay the sentence appeals until the SCCRC makes a decision.
The bombing of a United States-bound Pan Am flight in 1988 with the deaths of 270 people is regarded as the worst crime in Scottish legal history.
After much diplomatic wrangling Megrahi and another Libyan, Al-Amin Khalifa Fhimah, surrendered and were put on trial in a special high security courtroom in the Netherlands.
Three judges heard the evidence without a jury in 2001 and found Megrahi guilty. Fhimah was acquitted.
Five judges then heard an appeal in 2002 from Megrahi and decided that the guilty verdict should stand.
The 55-year-old former intelligence officer is now in Greenock Prison.
