doubtful questions and complaints of wrongdoing; men who will not stray either  to the left or the right from the straight path of justice1 for material prosperity or  fear of adversity, but who will judge the people of God equitably,2 so that one may  say of them, with the psalmist, that from their countenance came forth the judgment  of equity.3 And let them consider effectually what is required by necessity,  what desirable by expediency, what allowable by license and what becoming to  honesty. Such a judgment delights the honour of the king,4 whose person they  represent as they sit in justice. Let them deny to none the benefit of the law, [nor  seek or accept reward from anyone, as was said above,]5 that each may freely  pursue his right, 6that the cause of the widow proceed freely before them, they be  counsellors to the orphan and the ward,7 they permit false actions to be brought  against no one, and that their ordinances and edicts be in accordance with the law  and the approved customs and with the common welfare. 8Before them let no one  be oppressed by the power of his adversaries9 but each proceed as his cause requires,  and let them refrain10 from unlawfulness, nor let hatred, 11partiality or favour turn  them from the threshold of just judgments,12 that it may be said of them, Thou  art just, O Lord, and thy judgment is right etc.13 Those who judge must also be  wise, that they need not beg soundness in judgment from others. 14If any man  witless and unlearned [presumes] to ascend the judgment seat, taking his ability  to do justice for granted, he shall fall from on high, as venturing to fly before he  has wings; to give such a one the power of judgment is in no way different from  putting a sword in the hand of a madman.15 And a judge ought not only to be  wise but strong, according to the saying of Solomon, Seek not to be made a  judge unless thou art strong in virtue, with the strength to break down iniquities,  lest thou quail before the face of the mighty and lay a stumbling block in the way  of thy activity.1617[and see what kinds of justices delegate there are, what their  power is, and how their power or jurisdiction may be determined].18
Of the kinds of justices.
 Some justices are major, general, permanent and of greater importance, who  remain at the side of the king and whose duty it is to correct the wrongs and errors of  all others. There are also other permanent judges, sitting in a place certain, that  is,19 in the bench, who determine all pleas for which they have a warrant,  all of whom begin to have jurisdiction after having taken an oath. There are other  justices, travelling from place to place, as from county to county, sometimes for  all pleas, sometimes for certain special pleas, as for assises only and [the delivery  of] gaols, who begin to have authority without an oath, when they have received  the lord king's writ of warrant. There are also justices appointed for certain [named]  assises, two or three or several, who are not permanent, and who lose their jurisdiction  once they have discharged their office.20
