The accused duly summoned in person must appear, unless he provides an excuse recognised as valid by the court before which he is summoned. The accused has the same obligation when it is established that, although he has not been summoned in person, he was aware of the regular summons concerning him in the cases provided for by articles 557,558 and 560.
If these conditions are met, the accused person who has not appeared and has not been excused shall be tried by a judgement contradictoire to be served, unless the provisions of Article 411 are applied.
If a lawyer appears to defend the accused, he must be heard if he so requests, even outside the case provided for in article 411.
