An immediate suspension of the St Emilion classification system has been demanded by four chateaux demoted in the September 2006 reclassification.

The move follows the successful legal challenge earlier this month to the 2003 Bordeaux cru bourgeois reclassification, which has been annulled.

The judgement on the calls for a suspension is expected late tomorrow (30th March) or Monday (2nd April). If it is given, the legal process will be fast tracked.

Demotion in the St Emilion classification, which is drawn up for periods of ten years, can knock at least a third off the price of the wine.

In total, seven chateaux are involved in the St Emilion challenge, but only four demanded the immediate suspension.
