There was evidence offered to the jury for its consideration that the plaintiff was the owner of the lots in question and that he deposited $1,000 with the bank under the terms of his alleged contract, so we need not be further concerned with that phase of the case. The more serious question that confronts us is: Did the plaintiff perform the contract as alleged in his complaint? If there was any evidence to suрport this contention, it was a question of fact to be submitted to the jury; but if no evidence was offered relative to that issue, it then becаme a question of law for the court to decide.
As we construe the contract plaintiff was obliged to exercise due diligencе in carrying on the litigation for the purpose of canceling the reassessments levied, and he had a reasonable length of time in whiсh to do so. The money was deposited with the bank for the benefit of plaintiff’s grantee, and De Yol was not permitted, under the terms of his agrеement, to allow-, the property to remain encumbered beyond a reasonable length of time. At the expiration of that time, оr when the plaintiff defaulted in the performance of his contract, Whitmer, or his successor in interest, had the right to demand of the bank that- thе
*601
money deposited be released for the purpose for which it Was intended:
Browne
v.
Rhode Island Mortgage & Trust Company,
21 R. I. 169 (
It is conceded that the plaintiff never discharged the liens against the property, but it is claimed that Monks’ alleged voluntary payment to the city, while the appeal was pending, inured to plaintiff’s benefit, and, in contemplation of law, was a performance of the contract by him. We cannot agree with this contentiоn. Monks’ payment was not voluntary, but was made for the protection of his property and to prevent its sale by the city to satisfy the liens against it. Monks was in no sense a mere volunteer:
Hoffman
v.
Habighorst et al.,
Ten years had elapsed since plaintiff deposited this money with the bank to secure performance of his agreement, and still the special assessments remained a charge upon the property. Under such cirсumstances we believe Monks had a legal right to do that which the plaintiff had contracted but failed to do. It is certain that plaintiff had nо right to demand of the bank the money deposited until he had shown a performance of the contract on his part. Indeed, it is certаin that plaintiff had no right to demand the money until he had settled his litigation. The defendant had no authority to release this deposit in 1908 to pay Monks ’ mortgage indebtedness, and acted at its peril in so doing; but the plaintiff is not in a position to complain until he has shown under the theory of his сomplaint a performance of the contract.
If after the bank permitted the money deposited to be used in satisfying the Clark mоrtgage, De Yol, within a reasonable length of time from the date of *602 deposit, had performed his part of the contract by having the municipal liens in question canceled, thereby clearing the title to the property which he had sold, then he would undoubtedly be entitled to prevail. If he was prevented from carrying out his agreement by the act of the defenedant, it should have been so alleged.
Under that thеory of the case his measure of damages would have been the difference between the sum deposited with interest and the amount he would have been obliged to pay in satisfaction of the liens had defendant not interfered.
Where performance of a contract has been pleaded, recovery cannot be had upon proof that performance was prevented or waived. It is a question of failure of proof:
Young
v.
Stickney,
As a general rule it is a question of fact for a jury whether a contract has been performed within a reasonable length of time, but when the facts are undisputed, as in the instant case, it then becomes a question of law for thе court to decide:
Paulson
v.
Weeks,
The trial court submitted this issue to the jury, but in our opinion would have been warranted in stating as a matter of law that a reаsonable length of time had expired in which plaintiff had to perform.
In the former trial a motion for nonsuit and directed verdict was denied, and this court in its prior opinion held that the court was right in submitting the case to the jury. It is now insisted that
*603
the law of the case has been settled in that resрect and by reasoii thereof we are precluded from considering the question as to whether there was evidence of performance of contract. The rule of “law of the case,” while similar to
res judicata,
has greater limitations and is applicable only when the same point was decided in the previous appeal.
Res judicata
and “law of the case” are distinguished in
Alerding
v.
Allison,
“The doctrine of ‘the law of the case,’ as referring to the decision of the court in a particular case on a former appeal, is analogous to the doctrine of former adjudication, but much more limited in its application. Under the rule of former adjudication, when a cause has been finally determined by a compеtent tribunal, all questions of controversy arising in the case must be taken as at rest forever, not only the things that were actually adjudged, but evеry other matter which the parties might have litigated under the issues formed:
Fischli
v.
Fischli
(1825), 1 Blackf. *360,
Defendant in the first trial moved for a nonsuit and directed verdict for the reason that there was no competent evidence that the contract had ever been
*604
made or that plaintiff ever made any deposit with defendant. The question as to the lеgal effect of plaintiff’s failure to show performance of contract as alleged has never before been presеnted for decision, and therefore we may properly consider the same:
Pacific Mill Co.
v.
Inman, Poulsen & Co.,
We are of opinion that defendant was entitled tо a directed verdict for the reason that plaintiff failed to prove performance of the contract as alleged. In viеw of this conclusion it is not necessary to consider assignments of error:
Rosenwald
v.
Oregon City Transp. Co.,
The verdict of the jury for the defendant is in keeping with the facts and law of the case, and the judgment based thereon is affirmed. Affirmed.
