*** Sir P. Home reports this case.1681. December.
James Wilkie and John Hamilton having granted a bond to Alexander Gray, writer in Edinburgh, for the sum of 500 merks, whereupon following there was an inhibition served, which being assigned to Adam Mitchel, he transfers the same to Robert Malloch, merchant in Edinburgh, who leads an adjudication of certain lands belonging to the said James Wilkie, which lands had been formerly disponed to Mr Isaac Whitelaw, but after the inhibition; upon which Mr Isaac raised a reduction and declarator against Robert Malloch for reducing of the bond and diligence done thereupon, upon this ground, that the land being disponed by James Wilkie to David French, who disponed the same to Mr Isaac Whitelaw, which albeit after the inhibition served at Alexander Gray's instance, yet the debt being properly due to David French, the pursuer's author, who is liable in warrandice of the disposition, and Alexander Gray's name being only borrowed to his behoof, he could not make use of that debt to affect the lands in prejudice of that person to whom he had disponed the lands, and to whom he was liable in warrandice; for he being both debtor by the warrandice, and creditor in the sum, confusione tollibatur, and so soon as the right of the sum came in French's person, it became so far extinct, as that albeit it were thereafter transferred to Adam Mitchel, who was French's brother-in-law, it could not affect the lands in prejudice of the clause of warrandice in the disposition; and it appears that the assignation has been taken blank by French ab initio, and been lying by him the time of his decease; and Malloch having thereafter named French's relict, they filled up Adam Mitchel their brother's name in the assignation, who thereafter transferred the same to Robert Malloch the defender, which was a manifest fraud and conveyance, and therefore craved, that Alexander Gray, Adam Mitchel, and the writer and witnesses of the assignation, may be examined ex officio upon the trust and other grounds above-mentioned, for clearing of the fraud and contrivance; as the Lords are ordinarily in use to do in such cases. Answered, That it is a principal in law, that writ cannot be taken away but by writ, or oath of party; for the defender having right to the sum for onerous causes, it cannot be taken away unless it could be made appear scripto of French that Alexander Gray's name was only inserted in the bond to his behoof, or by the defender's oath, that it consisted with his knowledge that the bond was granted to Alexander Gray in trust; for albeit the Lords, in some cases, ex nobilio officio, before answer, do examine witnesses, in order to the taking away of writ, where there are evident presumptions of fraud, or when writs have been depositated, or have been lying by the party the time of his decease; which cannot be pretended in this case, where it is evident by the bond, that it is all written with John Hamilton's own hand, who is one of the parties bound in the bond with Wilkie; and David French is witness to the bond, and it cannot be supposed that if the bond had been taken blank in the creditors' name to his behoof, that he would have been a witness in the bond; and Alexander Gray was altogether a stranger to David French, and it cannot be supposed that if the bond had been taken blank in the creditors' name to his behoof, that he would have intrusted a stranger's name in the bond, without a back-bond; and the assignation to Adam Mitchel is three years after the bond, so that it was not lying blank by him the time of his decease; as also, it is a principle in law, that a cedent's oath cannot be taken in prejudice of the assignee, especially the assignation being for an onerous cause; and if it were otherwise sustained, it would lay a foundation to subvert a great point of the securities in Scotland. The Lords, before answer, ordained Alexander Gray, Adam Mitchel, and the writer and witnesses in the bond, to be examined upon the foresaid grounds of declarator, but in respect he was informer, and might tyne or win in the cause, and that there were several other objections against him that might debar him from being a witness, the Lords discharged him to be a witness.
