There are concerns a high profile dissident republican could be planning to breach his bail while on holiday.
Dee Fennell's conditions were temporarily changed to allow him to visit Donegal for one week.
The 34 year old from Torrens Avenue in Belfast is currently accused of offences linked to promoting terrorism including allegations gave a speech encouraging support for the IRA.
Its feared he may attempt to attend a hunger strike commemoration in Bundoran on Saturday.
MP Tom Elliott has questions for the authorities.
"Whilst the decision to vary Mr Fennell’s bail conditions is surprising, the timing of Mr Fennell's holiday is not, given that it appears to coincide with the annual Republican Sinn Fein hunger strike commemoration in Bundoran.
“This decision gives Mr Fennell the opportunity to repeat the offences for which he is currently charged, namely encouraging acts of terrorism and inviting support for the IRA.
“I would therefore ask whether any specific condition was placed on Mr Fennell to exclude him from Bundoran next Saturday? And if not why not?” he added
