For the space of two months the commons and the House of Lords engaged themselves in conference and separately in the consideration of a petition defining, the rights asserted in the resolutions. On the part of the commons the chief advocates were Selden, Littleton, and Digges; Sir Edward Coke, whose unwillingness to bend the judicial knee to King James had procured his dismissal long since from the chief-justiceship; and Noy, the genius who was shortly to turn against the Commons and in his invention of ship money furnish a means whereby to lay taxes without parliamentary assent. The interest of the crown was defended by attorney-general Heath and Sergent Ashley. The king was in a dilemma; he could not permit the petition to be brought in, in parliamentary form, and he could not dissolve Parliament without losing five subsidies which the commons had signified their willingness to grant him.[339] He therefore tried to steer a middle course; he offered to Parliament his royal word not to imprison unjustly and expressed his willingness to confirm the charters. Coke, however, insisted upon a specific statement of issues; any such hazy settlement of difficulties as the king proposed was unlikely to be permanent; definiteness was essential. To that end he proposed the drawing up of a Petition of Right. [The Petition of Right] When the instrument was at last drawn up, it was sent to the House of Lords. The lords attempted to introduce an amendment designed “to leave entire that sovereign power,” as the proposed change itself ran, “wherewith your Majesty is trusted for the protection, safety and happiness of your people;”[340] but the commons would have none of it, and at last the lords yielded their assent. The king at first gave a cumbersome, evasive answer to the petition which was in reality no answer at all,[341] and roused thereby a storm of indignation, which exhibited itself in a movement to censure Buckingham. This the king averted by signing the Petition of Right in the usual manner, and received in consequence his five subsidies.[342] [The statutes cited in the Petition]
