The Commons also passed a series of constitutional reforms, including the Triennial Acts, abolition of the Star Chamber, and an end to levying taxes without Parliament's consent. Voting as a block, the bishops ensured all these were rejected by the Lords. In June 1641, Pym secured passage of the Clergy Act in the Commons; one of its key provisions was to remove bishops from the Lords, which therefore rejected it. The growing political tension was brought to head in October with the outbreak of the Irish Rebellion. both Charles and Parliament supported raising troops to suppress it, but neither trusted the other with their control, fearing any army would be used against them first.
