Its long title was "An Act for the more easy and speedy Trial of such Persons as have levied, or shall levy War against His Majesty; and for the better ascertaining the Qualifications of Jurors in Trials for High Treason or Misprision of Treason, in that Part of Great Britain called Scotland.

Under common law a trial had to take place in the county where the crime happened.

This exception to the rule had first been introduced as a temporary measure in 1715, during the first Jacobite Rising.

2. c. 26, stated that people named in the Act would automatically be attainted of treason unless they surrendered to the authorities by 12 July 1746.
