“For the purpose of constructing the undertakings of both parties it was necessary that ground should be acquired on the foreshore to the west of what was then Inchgreen Island. This stretch of land was owned principally by the pursuers and the five persons named in the third article of the agreement. Much of the ground was submerged at high water, and some of it, including what belonged to the pursuers, was used as timber ponds into which the timber was floated at high water and left lying in the mud at low water. Access to these timber ponds was obtained by what were termed ‘water passages.’ These passages did not differ from any other portions of the foreshore except in so far as they were indicated by a row of stobs on each side which served both to mark the passages and to guide the timber into the ponds. At the extreme west end of the ground there were two plots belonging to the Clyde Pottery Company and to William Watson, which were separated by a street called Pottery Street extending from the high road between Greenock and Port Glasgow down to low water-mark. This street had never been properly formed.
“For their undertaking, which included the construction of a quay wall, the pursuers required the seaward portion of the ground in question along its entire length, and they ceased to have any use for the plots 5 and 6 on the plan, which had been feued by the pursuers from the superior and were let as timber ponds. On the other hand, this area and the contiguous ground to the west were required for the Railway Company's lines and other works. Accordingly in the agreement a line with the lettering C, D, E, F, G, was drawn through the foreshore in a direction from west to east; and the general scheme of the agreement was that the pursuers were to have the whole ground to the north of this line while the defenders took the ground between the line and the road to Port Glasgow. For both parties it was essential that they should be fully vested in the property of their respective portions of the land in question.
“After the agreement had been executed the defenders proceeded to acquire under their compulsory powers the properties belonging to the five persons named in article 3. The price of one of the properties was settled by agreement, the prices of the others were all determined by the award of arbitrators or juries under the Lands Clauses Act. It then occurred to the defenders that neither they nor the pursuers could obtain a complete title to the whole lands required unless they got a disposition of the solum of the water passages from the superior. They differed as to the price to be paid—the defenders maintaining that the solum of the passages, burdened as it had been with a right of access to the timber ponds, was valueless, while the superior demanded a substantial price. This matter also was referred to arbitration, and on the defenders paying the sum awarded by the arbiter a disposition was granted in their favour which completed their right of property in the passages in question. Meanwhile both parties were engaged in constructing their several undertakings; and since Whitsunday 1885 each has been in possession of the ground on the north and south respectively of the line C, D, E, F, G. The conveyances to be granted under the agreement have never been adjusted; nor have the prices payable been settled. This great delay may be explained in various ways, but is I believe mainly due to the different views taken as to the meaning of the agreement. After protracted negotiations parties have failed to come to terms, and the pursuers have now brought this action to have the various matters in dispute settled by a court of law.”
“While the Lord Ordinary seems to indicate that he held the defenders liable to pay interest because they were responsible for the delay in completing the transaction, and therefore in fault, this is not the ground of the decision in the Inner House, In point of fact the delay was due to the breakdown of the original agreement, and to the knowledge of both parties that it could not be applied to the facts as ascertained after its date, without equitable adjustment, or at least without getting it judicially construed. The delay which took place in taking steps towards adjustment or towards obtaining judicial construction was, the appellants maintain, attributable to the respondents. That the appellants were not in fault is evident from the correspondence, which shows in particular that on1st April 1891 the respondents asked the appellants for a tracing of the ground the respondents had to acquire from the appellants, and on 5th June thereafter the appellants sent the respondents the plan required by them, and notwithstanding this no claim was made by the respondents against the appellants from the date of the agreement in 1881 until March 1902, a period of twenty—one years. There is no evidence of an oral character of any fault on the part of the appellants. The representative who instructed the negotiations on their behalf is dead, and the evidence of the respondents' secretary and general manager does not reveal fault on the appellants' part when read along with the correspondence. The ground upon which the Inner House put the finding for interest is that by the law of Scotland, in the case of an ordinary sale of heritage, the purchaser is ex lege bound to pay interest for the price of the subject bought from the term at which he enters
