¿Se pospondrá el juicio de Rachida Dati y Carlos Ghosn el 16 de septiembre?

Por qué: Multiple independent news outlets in the supplied evidence report that the trial opened on 16 September 2026 and that Carlos Ghosn was absent though he had requested a postponement; none of the supplied sources report that the presiding judge ordered an adjournment at the opening session. For example, TV5Monde (AFP) headlined that the trial "s'est ouvert, en l'absence de Carlos Ghosn", OCCRP said criminal proceedings "began Wednesday", Franceinfo's live coverage reports the hearing opening at 13:30 and that Ghosn had sought a deferral, and Le Monde and RFI likewise report the trial starting while noting Ghosn's request. The consistent, corroborated account across these independent outlets is that the opening session proceeded rather than being formally postponed by the judge, so the answer is NO.
