Parties' preferences have not been disclosed, though unofficial information suggests there are two likely options: either his status will be revoked or it will be suspended for the duration of his two-year prison sentence.

These are two of the three possibilities provided to MPs by their in-house legal service and a special task force of jurists into which parties were asked to nominate a member each (the SDS and New Slovenia (NSi) did not).

The other options are to leave Janša's status as it is, or as an alternative proposed by several jurists not on the task force, to let him stay on as MP and suspend his prison sentence for the duration of his lawmaker status.

Janša's status is highly disputed, as he is serving a two-year prison sentence for corruption, which leads to automatic revocation of MP status.

But a narrow interpretation of the law suggests this is the case only for MPs found guilty while in office, which is not true in the case of Janša, who received the guilty sentence before he became MP.

While the commission's opinion will be cue for the vote at the plenary, it is widely believed the matter will end up in court, which Janša and his party have said would have the final say.
