form et execution creating that et submissionis in  ead mention idem robertus petit judgment c upon which the defendant do  demurrer in law and in this case point be resolve that although William wild  the defendant be bind in a bind to stand to abide observe the rule c  arbitrament c yet he may countermand the same for a man can by his act make  such authority power or warrant not countermandable which by the law and of  his nature iscountermandable as if I make a letter of attorney to make livery  or to sue a action in my name or if I assign auditor to take a account or if I  make one my factor or if I submit myself to a arbitrament although that these  be do by express word irrevocable yet they may be revoke so if I make my  testament and last will irrevocable yet I may revoke it for my act or my word  can alter the judgement of the law to make that irrevocable which be of its  own nature revocable and therefore where it be say in Edward b if I be bind to  stand to the award which I S shall make I can not discharge that arbitrament  because I be bind to stand to his award but if it be without obligation it be  otherwise it be resolve that in the one case or the other the authority of the  arbitrator may be revoke but then in the one case I shall forfeit my bind and  in the other I shall forfeit nothing for ex to make naked submission non  be born act and therewith agree brook in abridge the say book of Edward b and  so the book of Edward be well explain vide Henry Henry b Edward a Edward  Edward it be resolve that the plaintiff needs not aver that the say William  rug have notice of the say countermand for that be imply in these word  to call again et to repeal all men  origination c for without notice it be no  revocation or abrogation of the authority and therefore if there be no notice  then the defendant may take issue quoth non to call again c and if there be no  notice it shall be find for the defendant as if a man plead quoth feoffavit  devoted to or to send down pro boundary vitae the same imply livery for  without livery it be no feoff gift or demise but there be a difference when  thing be requisite to the performance of a act and both thing be to be do by  one and the same party as in case of feoff gift demise revocation countermand  c and when two thing be requisite to be perform by several person as of a  grant of a reversion attornment be not imply in it and yet without attornment  the grant have not perfection but for as much as the grant be make by one and  the attornment be to be by another it be not imply in the plead of the grant  of one but in the other case both thing be to be do by one and the same party  and that make the difference and therewith agree Henry a where William bridge  bring a action of debt for upon a arbitrament against William Bentley the  defendant plead that before any judgement or award make by the arbitrator the  say William Bentley discharge the arbitrator at Coventry in the county of  Warwick and the same be hold a good bar and yet he do not aver any notice to  be give so it be adjudge in Henry Henry c it be resolve that by this  countermand or revocation of the power of the arbitrator the obligee shall  take benefit of the obligation and that for two cause because he have break  the word of the condition which be that he shall stand to and abide c the rule  order c and when he countermand the authority of the arbitrator he do not  stand to and abide c which word be put in such condition to the intent that  there shall be no countermand but that a end shall be make by the arbitrator  of the controversy and that the power of the arbitrator shall continue till he  have make a award and when the award be make then there be word to compel the  party to perform it sure observe perform fulfil and keep the rule order c and  this from be invent by prudent antiquity and it be good to follow in such case  the ancient from and precedent which be full of knowledge and wisdom and with  this resolution agree the say book of Edward b which be to be intend as above  say ut above that the obligor can discharge the arbitrament but that he shall  forfeit his bind and the book give the reason which be the cause of this  resolution scilicet because I be bind to stand to his award sure to stand to  his award which I do not when I discharge the arbitrator the other reason be  because the obligor by his own act have make the condition of the obligation  which be endorse for the benefit of the obligor to save he from the penalty of  the obligation impossible to be perform and by consequence his obligation be  become single and without the benefit or help of any condition because he have  disable himself to perform the condition vide Edward per choke Edward b a if  one be bind in a obligation with condition that the obligor shall give leave  to the obligee for the time of year to carry wood c in that case although he  give he leave yet if he countermand it or disturb the obligee the obligation  be forfeit and afterward judgement be give for the plaintiff
