The complaint stated in substance, as follows:
The defendant is a real estate broker. During the month of June, 1945, plaintiff was “approached by defendant Allison with reference to buying said property” (the property in suit) from the owner, who resided in California.' The plaintiff advised the defendant that he would buy it for $3 per acre “and after further conference, defendant offered to act for plaintiff and secure a deed for the land, free of encumbrances, for $3 per acre, from the owner.” Plaintiff accepted the offer and authorized the defendant to negotiate with the owner and procure a deed from him to plaintiff. The land was a desirable purchase for plaintiff at said price ($3 an acre) “and even a higher price.” The defendant disregarded his duties to the plaintiff and negotiated a purchase for himself, and placed in the deed the name of one Shearman for the purpose of fraudulently retaining the mineral rights in the land. At that time the defendant knew the mineral rights could be sold for $3 an acre and “in said transaction defendant dealt for himself and double-crossed both the owner and this plaintiff.” The defendant as a broker, attempted to serve both the seller and the buyer without a disclosure of his conduct in the matter, and to procure for himself the mineral rights, and by such self-dealing beat both the seller and his client (the plaintiff) out of the price of such mineral *59rights. The plaintiff was damaged in the sum of $1600.00. By a bill of particulars asked for by defendant, plaintiff stated that the contract was oral and that plaintiff agreed ,to compensate the defendant for his services as purchasing agent, with payment of the customary commission therefor.
It was held by this court on the first appeal that the allegations above recited stated a cause of action, and this is the law of the case. First Nat’l Bank of El Paso v. Cavin, 28 N.M. 468, 214 P. 325. The case was tried to a jury, which returned a verdict in favor of plaintiff for $960.00, in which amount judgment was entered. From this judgment defendant has appealed.
It is asserted that the plaintiff did not prove facts that would support this judgment. If facts proved establish the above allegations, then the plaintiff is entitled to recover, whether the law of the case, as we have stated it in the first opinion, is right or wrong. In other words, if the plaintiff proved the facts alleged in his complaint, he was entitled to his judgment.
There is substantial evidence that supports the following facts:
In June 1945 (no specific day was stated) plaintiff employed the defendant, who at the time was a real estate broker, to purchase for him the land in question, including all mineral rights; and agreed to pay therefor as much as $3 per acre. It was agreed that plaintiff would pay defendant the usual commission, which was five percent of the purchase price. The defendant said he would see what he could do. At ■that time the defendant was the agent of the owner, Dr. Konigmacher of Fresno, California, for the sale of this property, but this was not disclosed to plaintiff, nor did Dr. Konigmacher know that defendant was also agent for plaintiff to negotiate a purchase for the land.
On the 29th day of May, 1945, the owner of the property (Dr. Konigmacher) sent by mail an abstract of title, and a deed conveying this property to one Dale Shearman, to the First National Bank of Roswell, with instructions to deliver them to defendant upon -the payment of $1164. The documents were in the bank on June 8, 1945, if not sooner. Nothing was said to plaintiff about this -situation at the time he employed the defendant to buy the property for him. Shearman was a partner of -the defendant and -the property was being bought for the two of them jointly. Defendant never advised the owner that Shearman was buying the property for both defendant and Shearman.
On July 7, 1945, the plaintiff made an abortive attempt to buy the property frtm Dr. Konigmacher directly, at $3 per acre. *60Later in July, Allison paid the First National Bank of Roswell $1164 and received the abstract and deed. Thereupon defendant offered to convey the land to plaintiff, reserving to grantor the mineral rights for $3 per acre, which offer plaintiff rejected, and this suit followed. There is no direct •testimony whether plaintiff would have paid $1164 for the land and abstract. We are satisfied from Dr. Konigmacher’s letters that he would not have sold it for less. Defendant fixed the value of the surface in his offer to plaintiff, at $3 per acre.
It was stipulated by the parties that the deed records of Chaves County show that Dr. Konigmacher deeded the land in question to Dale Shearman; that Dale Shear-man deeded the land, reserving all minerals, to Charles E. Ritter; that Dale Shear-man deeded to plaintiff a one-half interest in the minerals, and that Shearman and Allison leased the mineral rights to the Richfield Company. There was testimony to the effect that the mineral rights were worth at that time from $2.50 to $4 an acre. The land (including minerals) assuming it was a full half section, was bought by Shearman and defendant for $3,325 per acre, plus $100 for an abstract of -title, a -total of $1164.00.
One employed as a real estate broker to purchase property for another is prohibited from purchasing the property for himself, Mitchell v. Allison, 51 N.M. 315, 183 P.2d 847; Bachrach v. Fleming, 269 Pa. 350, 112 A. 445; Quinn v. Phipps, 93 Fla. 805, 113 So. 419, 54 A.L.R. 1173. It is held that a selling broker cannot sell to a partner, Baird v. Conover, 66 Okl. 288, 168 P. 997, without a disclosure of the facts to his principal, and without securing his consent -thereto; and the same rule should apply to one employed to buy property.
After the purchase of this property, it was held by defendant and Shear-man as constructive trustees for plaintiff.
“A person in a fiduciary relation to another who purchases property for himself individually may be chargeable as constructive trustee of the property, even though he purchases it from a third person and not from himself as fiduciary. He is chargeable as a constructive trustee where he purchases for himself individually property which he should purchase for the beneficiary * * 3 Scott on Trusts, Sec. 499.
But it is said that the property could not have been bought for $3 per acre, the maximum price fixed by plaintiff. The defendant was under a duty to have informed plaintiff of this fact, and to inform him the price asked by the owner, and thus have given him an opportunity to purchase at the seller’s price. Quinn v. Phipps, supra. From the value placed on the land by the plaintiff, jury, and witnesses, we are *61satisfied plaintiff would have bought at the increased price if he had been given that opportunity, to which he was entitled.
The land and mineral rights were sold to others, leaving plaintiff only the remedy of an action at law. The evidence supports the allegations of the complaint, which we have held states a cause of action.
It should be stated that the defendant denies that he was ever plaintiff’s agent, and supported his case by persuasive testimony; but the jury elected to accept plaintiff’s evidence upon the question.
It is asserted that plaintiff made no demand upon defendant for payment of damages in this case, prior to bringing suit and that such demand is required by Sec. 53-703, N.M.Sts.1941, which is as follows: “No contract for labor, or for the payment or delivery of property in which the time of performance is not -fixed, can be converted into a money demand until a demand of performance has been made and the maker refuses, or a reasonable time is allowed for performance.” Assuming that this action comes within the statute, the question was not raised in the district court and will not be considered by us for that reason.
. Also, it is said that the trial court erred in giving to the jury instruction number 7. No exception or objection was made to this instruction. The trial court was not advised of the error, if indeed it was an error, so that he could correct it.
The orderly administration of law and the expeditious trial of cases require definite rules of procedure in appellate practice, and that they be enforced without favor. Unless the trial court’s attention is called in some manner to the fact that it is committing error, and given an opportunity to correct it, cases will not be reversed because of errors which could and would have been corrected in the trial court, if they had been called to its attention. In -the hurry of trial work such errors are common, and one who is not satisfied with a ruling of the trial court should call to its attention the fact that it may be committing error, thus giving an opportunity to correct the ruling, if, in the light of the objection or exception, it should conclude that such ruling was error. It is, therefore, a general rule that the failure to so advise the court is a waiver of the right to object or present such question for review in the supreme court and it is provided for by supreme court rule XX, 1941 Comp. § 19-201, as follows:
“1. None but jurisdictional questions shall be first raised in the Supreme Court.
“2. Formal exceptions shall not be required in any case, but to preserve the question for review it must appear that a ruling or decision by the trial court was fairly invoked.”
*62Notwithstanding Rule XX the supreme court, in the interest of justice, has not limited to jurisdictional questions those that can be first raised in the supreme court. In Candelaria v. Gutierrez, 30 N.M. 195, 230 P. 436, it was said that there were three exceptions to the general rule, to-wit: (1)-Jurisdictional questions; (2) Questions of a general public nature affecting the state at large, and (3) questions affecting the fundamental rights of a party. Also see Kemp v. Williams, 30 N.M. 299, 232 P. 1078; Springer Ditch Co. v. Wright, 31 N.M. 457, 247 P. 270. Whether coming within the three exceptions stated in the Candelaria case, we need not pause to consider, but the supreme court has also held that the general rule does not apply in the following cases: When the judgment appealed from is inherently and fatally defective, State ex rel. Burg v. Albuquerque, 31 N.M. 576, 249 P. 242; where a person is convicted and sentenced to imprisonment for a term of years without evidence to support the verdict of •the jury, and the evidence conclusively established his innocence. State v. Garcia, 19 N.M. 414, 143 P. 1012; the question of the constitutionality of a criminal statute for the violation of which a person has been convicted and sentenced to the penitentiary. State v. Diamond, 27 N.M. 477, 202 P. 988, 20 AX.R. 1527.
The judgment of the district court should be affirmed, and it is so ordered.
