JURISDICTION AND PRACTICE

Of the Court of the Vice-Warden of the Stannaries of Cornwall.

BY H. S. STOKES, ESQ.

THE Court of the Vice-Warden is of great antiquity, and it now exercises the common-law jurisdiction which for centuries was vested in the Stewards of the Stannaries, and whatever common law or equitable jurisdiction the Vice-Warden of the Stannaries formerly possessed. Those who are curious to inquire into the extent and nature of the powers anciently held by the Stewards and the Vice-Warden, are referred to Mr. Smirke's report of the case of Vice v. Thomas, determined on appeal before his Royal Highness Prince Albert, the present Lord Warden of the Stannaries, and the collection of records and documents which Mr. Smirke has appended to his report, with valuable notes and illustrations. The object of this article being to describe briefly the present jurisdiction of the Vice-Warden, and the practice of the Court, it may suffice to state, in reference to the origin and authority of the Court, that it is founded on immemorial customs, declared from time to time by Convocations of Tinners, and confirmed, defined, and extended by Royal Grants and Acts of Parliament.

In the year 1835 the Court, which had for some time been in abeyance, was remodelled and almost reconstituted by the legislature. An outline of the more important statutory provisions

will, therefore, be given; to be followed by a description of the persons and matters within the jurisdiction of the Court, and some account of the proceedings of the Court and the mode of appeal to the Lord Warden.

I. The statute that most affects the Stannaries is the 6 & 7 Wm. IV., c. 106, by the first section of which it is declared that it shall be lawful for the Duke of Cornwall for the time being, if of full age, or his Majesty and his successors, King or Queen regnant of England for the time being, if there be no Duke of Cornwall, or if the Duke of Cornwall for the time being is under age, to appoint from time to time a fit person, being a barrister of at least five years' standing, to be the Vice-Warden of the Stannaries.

By the fourth section of the same Act it is enacted, that the original equitable jurisdiction theretofore lawfully exercised shall thenceforth be exercised by the Vice-Warden for the time being, not only in respect of tin and tin mines, to which it was formerly confined, but in all matters and things brought before him, so far as relates to the working, managing, conducting, or carrying on of any mine worked for any lead, copper, or other metal or metallic mineral within the said county of Cornwall, or to the searching for, working, smelting, or purifying of any lead, copper, or other metal or metallic mineral, within the said county, in as full and ample a manner as if the same had related to any tin or tin ore, or tin mine, or mine worked for tin in the said county."

By the fifth section it is provided, that it shall be lawful for the Vice-Warden to rehear and vary his own decrees, orders, and acts, and that the Lord-Warden shall have power on appeal, with the aid of three or more members of the Judicial Committee of the Privy Council, to affirm, alter, or reverse the decrees, orders, or acts of the Vice-Warden, and to dismiss the appeal with costs or otherwise, as may seem just; and that the judgments of the Lord Warden shall be subject to appeal to the House of Lords.

By the sixth section the common-law courts of the Stannaries are consolidated into one court, to be held before the Vice-Warden; and the seventh section declares that the Vice-Warden shall have

and exercise the same common-law jurisdiction and the same power and authority in all matters brought before him in any way connected with the working, managing, conducting, or carrying on of any mine worked for any lead, copper, or other metal or metallic mineral in the county of Cornwall, or the searching for, working, smelting, or purifying of lead, copper, or any other metal or metallic mineral in the county, in as ample a manner as if the same had been connected with or related to any tin or tin ore or tin mine, or mine worked for tin; and the right is given to any party, plaintiff or defendant, to appeal against any judgment, order, or sentence, to the Lord Warden, who, aided by three or
