delivered the opinion of the court:
The first error urged here is, that the court below erred in admitting any evidence in regard to the matters claimed to have been admitted and confessed by the six special pleas. It is urged by appellant that the averments in these pleas were binding on the appellee as admissions of record, and that appellee could not be heard to contradict or explain these admissions by any evidence whatever. Numerous cases are cited to support this contention, but they are not in point and do not apply to the state of the pleadings in this case. It is said in Chitty that “the common doctrine that a demurrer admits the facts stated in the pleading demurred to, must be understood with this qualification: that it is so only on the argument, for it has been held that the statements in a special plea which has been holden bad on demurrer are not evidence for the plaintiff on the general issue, although the jury are to assess damages as well as to try the case on the general issue.” (Chitty’s Pl. *662.) These *578special pleas were held bad on demurrer, and the act of the defendant in standing by them had no further effect on the trial below. The only effect was to reserve the question of the sufficiency of the pleas for appeal or error. For the purposes of the trial below they were demurred out. The evidence was proper under the general issue.
The plaintiff tried his case on the theory that these pleas admitted the reception by the defendant of the moneys as charged, for the use of the plaintiff, and he gave no evidence in chief of any services rendered by him for the State at the defendant’s request, nor of their value. This being an action to recover for money had and received by the defendant to the plaintiff’s use, it devolved on the plaintiff to prove that the defendant held money which ex cequo et bono he ought to pay to the plaintiff, the usual test being, does the money in justice belong to the plaintiff. (First Nat. Bank v. Gatton, 172 Ill. 625, and cases there cited.) In order to show that the money which was received by the defendant in justice belongs to him, the plaintiff in this case, it was incumbent on him to prove that he had rendered the services for which he claimed payment and that he had not been paid for them. In order to support his contention that the defendant had received money that belonged to him, he introduced in evidence six vouchers, bills or statements of account, with certificates attached, from the files of the State Auditor’s office. Each statement or bill is headed, “State of Illinois, to M. T. Moloney, Attorney General, Dr.,” and begins (with one exception): “To moneys contracted for, advanced and paid out by me, under my order and direction, in the discharge of the duties imposed on me by law, on account of the legal expenses of the insurance department.” One of the bills begins as follows: “To moneys advanced for legal and incidental expenses incident to the discharge of his duties in relation to the insurance laws of the State.” Each *579of these bills contains an item for services rendered by-Samuel Richolson in attending to insurance cases for the State of Illinois, some of them stating the per diem at §20, others only stating a lump sum, the total amount of these items being §9560. Each bill was certified to, substantially as follows: “I, M. T. Moloney, Attorney General, do hereby certify that the foregoing bill of M. T. Moloney, Attorney General, is correct and is payable from the appropriation for the legal expenses of the insurance department.—M. T. Moloney, Attorney General,” and was approved by the Governor. On these certificates appellee received warrants, by which he drew the moneys from the State treasury. Appellant contends appellee is estopped to contradict the statements made by him in these certificates in his official capacity, as Attorney General, under the sanction of his official oath.
The defendant was permitted to state in his evidence, over objection, that he made no contract with the plaintiff for legal services; that the way he came to make out his bills to the State, with items for Richolson’s services, was this: that there was a controversy between the Attorney General and the superintendent of insurance as to how the money appropriated for the legal expenses of the insurance department should be drawn out of the State treasury; that the Governor would not approve his (Moloney’s) bills unless the superintendent of insurance would certify them; that he (Moloney) had advanced money out of his own pocket for the State of Illinois, and had not been able to get any money on the appropriation for 1893 for a year and a half, and that the superintendent of insurance insisted that “legal expenses” meant attorneys’ fees, and nothing else; that after detailing these facts to Richolson, he (Richolson) then said to him, (Moloney,) that in order to obviate everything that had been said by the superintendent of insurance, and in order that he could have no possible excuse, as defendant had paid out the money, he should in the future draw it in the *580plaintiff’s name, as he was an attorney, and put it in as a per diem, as he saw fit, so as to cover the amounts of money he had expended. On cross-examination the defendant testified that the vouchers and certificates were false in so far as they professed to give a statement of the services rendered by the plaintiff in insurance matters, except as to what he had actually earned. The plaintiff denied that he ever made the suggestions testified about by the defendant, and said he knew nothing about the manner of drawing" these moneys at that time, and that there was no contract with him for $20 a day. These questions of controverted fact have been finally settled against appellant, but the testimony is mentioned here as bearing upon the question of estoppel raised by appellant.
An estoppel may be defined, in a general sense, to be a preclusion of a person to deny the truth of a fact which has been admitted or determined under circumstances of solemnity, such as by matter of record or by deed, or which he has, by an act in pais, induced another to believe and act upon to his prejudice. (11 Am. & Eng. Ency. of Law,—2d ed.—387; Hefner v. Vandolah, 57 Ill. 520.) There can be no estoppel in pais in this case, as appellant’s testimony above quoted shows that he knew nothing about these vouchers and certificates at the time they were made out, and it is not shown that he had ever acted in reliance upon them prior to bringing his action.
Appellant claims that these certificates attached to these bills were made under the sanction of appellee’s official oath, and that he is therefore estopped from denying them. Cases arising under deeds or bonds, where others have acquired rights under such deeds or bonds which it would be against equity and good conscience to allow to be disturbed by the parties making such deeds or bonds, cannot control here. No rights have accrued to any third parties under these certificates. The mere recital in these bills that certain sums were due from the *581State to the Attorney General for services rendered by appellant would not entitle appellant to recover on them, even if these recitals are certified to under the sanction of an official oath. They are but statements that the State is indebted to the Attorney General for these items, and that these items arose out of the services which are therein stated to have been rendered by appellant; non constat, but that these services have already been paid for by the appellee. Most of the bills read, “to moneys contracted for, advanced and paid out.” One of them reads, “to moneys advanced.” The certificates are that the bill is correct. It does not appear anywhere from the face of these bills whether any of these items are still to be paid by the Attorney General or whether they have all been paid. Appellee admitted in his testimony that appellant had rendered some services to which some of these items might apply, but denied their specific correctness, and claimed that he had settled in full with appellant for his services. Whether these services had been paid or settled for by the Attorney General was a question of fact to be tried by the jury.
There is no error in the instructions given for appellee covering the services rendered to the State for appellant. The instructions refused for appellant on this point all contain the vice that they assume that appellee admitted that he received these moneys -for appellant by his six special pleas. There was a direct conflict of evidence as to the terms on which appellant should render services to appellee in matters personal to appellee, and in view of this fact the instructions on that branch of the case were proper. The seventh refused instruction is but an elaboration of the third instruction given for appellant and fully covered by the same.
Finding no error in the record the judgment of the Appellate Court will be affirmed.
Judgment affirmed.
