Parliamentary Procedure is a set of customs, rules, and regulations meant for the operation of both houses of Parliament. These procedures are essentially in the hands of the interlocutors of both houses, the Lord Chancellor and the Speaker of the House. The Great Charter of Valyria has some mentioned stipulations about the timeliness and orderliness of how these interlocutors may introduce legislation for discussion, but otherwise, most of the rules of the House will be established over time and built upon by successive interlocutors.
Two more specific clauses of the Great Charter mention some limitations on Parliamentary power in certain matters. Section 2 contains:
“…bills or acts whose subject matter shall center on taxation, war, or treaties shall require a supermajority of two thirds of all lords or ministers in attendance to pass each House.”
“...we shall acquiesce to the override of our royal veto or to a vote to make a change to this Great Charter if each House will approve by a majority vote of three fourths.“
