A by-election was held for the New South Wales Legislative Assembly electorate of Blayney on 12 January 1907 because Paddy Crick (Progressive) resigned from Parliament after findings of corruption made by a Royal Commission.

[1] Crick had also been expelled from the Legislative Assembly for outrageous behaviour in the chamber, however he was returned in the resulting by-election.

Instead the assembly amended its standing orders and suspended Crick pending the outcome of his criminal trial.

[3] The jury was unable to reach a unanimous verdict,[4] and the Attorney General declined to prosecute the matter again as evidence before the Royal Commission had been ruled inadmissible in his criminal trial.

[3] Crick then submitted his resignation from parliament, however before it was accepted the assembly passed a motion that he was guilty of conduct that rendered him ineligible to sit as a member.
