He was trialed by military court, which he felt unauthorized and illegitim to judge, he voiced his reservation. Among others they also accused him to incite the Viennese revolution of october 6th and the death of Latour, Imperial Minister of War, when he wasn't Hungary's Prime Minister anymore.
He was transported to Laibach (Ljubljana) while under way the civilian population twice recognized him and tried to free him, both in Hungary and Styria. Himself, believing in his innocence, asked the people to stop and leave him, he won't be found guilty.
The investigation and trial was not fair. He tried to get a lawyer - the widely acknowledged Deák Ference, who later played important political role - which they denied of him. He tried to get a copy of decrees and other documents him and his government issued and the national assembly created, he was denied. He called for witnesses, but since they were all high ranking officials, even King Ferdinand himself, they were all denied from him, and the lower ranking ones, the court never listened them. He was denied all the tools he could try to build his own defence. On the other hand all the accusations and unknown witnesses testimonies were accepted as facts. 
Despite all this when he was took to Olmütz, for the charges he was found innocent, but they could not let him go so the court there sentenced him to few years prison. Then the Minister-President of the Empire, Prince Felix Schwarzenberg told the court that since they did not find him guilty there is no basis to keep him in prison. He ordered them to sentence him to death which then the Emperor can give public pardon for as was customary in such cases. However right at the time as Schwarzenberg issued this decree, Batthyány was transported to Pest from Olmütz. And at Pest it wasn't the Emperor who could give the pardon, but Haynau, the plenipotentiary military commander of the defeated Hungary was. And Haynau has no issue with refusing to give pardon, taking the blame for it, instead of the Kaiser.
