A lawyer for the 57-year-old said she was first questioned 18 months ago about allegations of supplying a mobile phone.
Peter Corrigan also confirmed a legal bid will be made to have the case against her thrown out as an abuse of process.
Price, also known by her married name of Marian McGlinchey, has been charged with providing property for the purposes of terrorism.
The allegation is related to the assassination of Sappers Patrick Azimkar and Mark Quinsey at Massereene barracks in Antrim in March 2009.
The soldiers were gunned down outside their base as they collected a pizza delivery.
Two men are due to stand trial accused of their murders later this year.
Price, who is in custody following the revocation of her release on licence, was expected to appear before Belfast Magistrates Court for a preliminary enquiry.
But she was not produced after it emerged that her defence team want to cross-examine three witnesses, including two senior detectives, as part of their challenge to the case against her.
A date for the day-long committal hearing is expected to be fixed next month.
Mr Corrigan told the court an abuse of process application will also be mounted.
He said: "The defendant was originally questioned in relation to these matters in November 2009. That's 18 months ago."
"No new evidence has been adduced since that date."
The solicitor detailed how his client's previous release from prison was subsequently revoked by the Secretary of State.
He claimed the allegations which formed part of the new charge against her were linked to that decision.
A hearing into the revocation of her licence is due to take place in August, the court was told.
"Why has it taken 18 months to make a decision to charge Marian McGlinchey with these offences?" Mr Corrigan asked.
"There must have been a decision taken at the time that there was insufficient evidence, (and now she is about to be released)."
District Judge Fiona Bagnall ordered that the case be listed again for August 5.
At that stage Price is expected to appear via video-link.
