The 1855 Victorian high treason trials took place between 22 February – 27 March in the aftermath of the Battle of the Eureka Stockade. The Goldfields Commission recommended a general amnesty for all on the runs from the fallen Eureka Stockade. Instead, thirteen of the rebels detained were eventually indicted for high treason. The juries all returned a verdict of not guilty by a jury, and the indictment against Thomas Dignum was withdrawn. On 23 January, the trial of Ballarat Times editor Henry Seekamp resulted in a finding of guilt for seditious libel, and a month later, he was sentenced to a term of imprisonment of six months. The trials have been described as farcical, and the colonial secretary would rebuke Governor Sir Charles Hotham over prosecuting the Eureka rebels for the lofty offence of high treason.

Goldfields Commission recommends general amnesty

On 14 December 1854, the Goldfields Commission sat for the first time. The first Ballarat session is held four days later at Bath's Hotel. At a meeting with Hotham on 8 January 1855, the gold fields commissioners made an interim finding that the mining tax be scrapped, and two days later made a submission advising a general amnesty be granted in relation to all those persons criminally liable for their association with the Eureka Rebellion.

Trial of Henry Seekamp

The first trial relating to the rebellion was a charge of sedition against Henry Seekamp of the Ballarat Times. Seekamp was arrested in his newspaper office on 4 December 1854 for a series of articles that appeared in the Ballarat Times. It has been speculated some of the offending articles were written by either John Manning, George Lang, the embezzling bank manager whose father was the prominent Republican and Presbyterian Minister of Sydney, the Reverend John Dunmore Lang, or Clara Seekamp, Henry's de facto wife. Seekamp was tried and convicted of seditious libel by a Melbourne jury on 23 January 1855 and, after a series of appeals, sentenced to six months imprisonment on 23 March. He was released from prison on 28 June 1855, precisely three months early. During Seekamp's absence, Clara would serve as editor of the Ballarat Times.

Eureka high treason trials

List of detainees at the Eureka Stockade

The approximately 120 detainees were mainly apprehended at or in the vicinity of the Eureka Stockade on the day of the battle. They marched to the Ballarat police holding cells until indictments could be issued or dropped. Most of the detainees faced a committal hearing presided over by a bench of magistrates. Depositions of crown witnesses for the brief of evidence in the high treason trials were taken between 7-9 December 1854 in Ballarat, mostly from soldiers and police officers who took part in the battle and other witnesses. Each deponent made a signed and sworn written statement concerning their knowledge of the facts concerning the indictment. The testimony was given in open court in the presence of the accused person, who was able to respond via submitting a statement of the accused, although this right was often waived by the detainees. Where the death of a person was involved, the proceedings became an inquest. The deponents were bound by recognisances to give evidence or a signed undertaking to appear at the trial for examination in chief at various venues if required.

Nothing is known about the status of most of the detainees regarding their actual participation in the armed uprising.
