Even if the conviction in the HIV case is upheld, a government-led Libyan body called the high judicial council can overturn it.

Bulgarian Prime Minister Sergei Stanishev said Libya's High Judicial Council will meet on Monday, which he said was a positive sign.

If reached, the agreement would be taken to Libya's High Judicial Council that has the power to amend or overturn decisions by the judiciary.

The case is expected to go to a government-controlled High Judicial Council which will have the power to commute the sentence or even pardon them.
