Resolutions for enforcing attendance of the Lords
All peers were required to attend the trial proceedings. As this document outlines, the only valid reasons for absence were: disability; age of 70 or upwards; being out of the country; or the death of parent, wife or child. The Lords' chambers did not have enough seating to accommodate the number of peers who were required to attend. Subsequently, new galleries with additional seating were constructed specifically for the trial.
