that every justice, except as is therein excepted, shall have 100_l._ _per annum_ clear of all deductions; and, if he acts without such qualification, he shall forfeit 100_l._ which[n] is almost an equivalent to the 20_l._ _per annum_ required in Henry the sixth's time: and of this qualification[o] the justice must now make oath. Also it is provided by the act 5 Geo. II. that no practising attorney, solicitor, or proctor, shall be capable of acting as a justice of the peace. [Footnote m: Lamb. 34.] [Footnote n: See bishop Fleetwood's calculations in his _chronicon pretiosum_.] [Footnote o: Stat. 18 Geo. II. c. 20.] AS the office of these justices is conferred by the king, so it subsists only during his pleasure; and is determinable, 1. By the demise of the crown; that is, in six months after[p]. 2. By express writ under the great seal[q], discharging any particular person, from being any longer justice. 3. By superseding the commission by writ of _supersedeas_, which suspends the power of all the justices, but does not totally destroy it; seeing it may be revived again by another writ, called a _procedendo_. 4. By a new commission, which virtually, though silently, discharges all the former justices that are not included therein; for two commissions cannot subsist at once. 5. By accession of the office of sheriff or coroner[r]. Formerly it was thought, that if a man was named in any commission of the peace, and had afterwards a new dignity conferred upon him, that this determined his office; he no longer answering the description of the commission: but now[s] it is provided, that notwithstanding a new title of dignity, the justice on whom it is conferred shall still continue a justice.
