He was accepted, and although his appointment delighted Murray, the government was very concerned at the loss of a good Attorney General. In an attempt to persuade him to stay, the new Prime Minister, the Duke of Newcastle offered him the post of Chancellor of the Duchy of Lancaster, in addition to the position of Attorney General, an extra £6,000 a year, and a pension, and finally attempted to blackmail him by saying that if he accepted the office of Lord Chief Justice, the government would refuse to grant him a peerage. It was customary for all Lord Chief Justices to be given a peerage, and Murray responded by saying that in that situation he would refuse to become either Lord Chief Justice or Attorney General. Newcastle gave in, and promised to allow him to become Lord Chief Justice and to recommend him for a peerage.
