Opinion by
Smith, J.,The principle that the lessee shall not be allowed to deny the title under which he has entered, and to hold possession against it, as illustrated in Holt v. Martin, 51 Pa. 499, in Snyder v. Carfrey, 54 Pa. 90, and in Bedford v. Kelly, 61 Pa. 491, is’not to be questioned. In those cases, the lessor described himself in the lease as “ agent ” or “ trustee,” and it was held that he might, as lessor, representing the title, recover possession at the expiration of the term, under the acts of 1772 and 1863.
But though the tenant may not deny that the landlord, had title when the demise was made, he may shoAV that this title has since determined: Newell v. Gibbs, 1 W. & S. 496.- And Avith respect to the payment of rent, where the lease is made by a lessor as agent or trustee, the tenant may show a revocation of the agency or trust, and a payment to tbe actual owner: Barrett v. Bemelmans, 163 Pa. 122. In the latter case, which Avas an action for rent by a part owner, on a demise by an agent described in the lease as “ trustee,” the land belonged to five persons, one of whom (Barrett) was appointed by the others “ as our agent or-trustee,” to lease and collect the rents. After he had leased to Bemelmans, Mrs. Bennett, one of the owners, revoked his authority to act for her, and gave the tenant notice to pay her one fifth of the rent. The tenant nevertheless continued to pay Barrett. It was held that Mrs. Bennett could maintain an action on the lease, in the name of Barrett to her use, for one fifth of the rent; .the Supreme Court, in an opinion delivered by Mr. Justice Williams, saying: “The question is, to whom, after the notice of revocation, should the tenant pay the accruing rent, so far as Mrs. Bennett’s share of it is concerned ? The tenant kneAV from the lease that Barrett was acting.for others, although their names were not disclosed in that instrument. Barrett knew that as to the interests of his cotenants, he Avas simply an agent, and that the terms of his agency gave him no interest in the subject-matter that would *392enable him to resist a revocation, as a fraud upon him. Upon these facts we think the following propositions are beyond any question: (1) Mrs. Bennett had a right to revoke the agency of Barrett whenever she pleased. (2) Barrett acquired, under the terms of the agency, no interest in the rent due to his principals other than that necessarily acquired by one authorized to collect money for another, and he had no right to object to the revocation of his authority at the will of his principals. (3) When this revocation was duly made, and notice thereof given to the tenant, the tenant was bound to take notice of the fact. No equitable or other right existed in the tenant to object to the revocation except as to acts done or rent paid before the notice was received.”
In the case before us, the lessor described himself in the lease as “ W. R. Kern, agent.” Thus, as in Barrett v. Bemelmans, “the tenant knew from the lease that Kern was acting for others, although their names were not disclosed in that instrument.” In defense of the action, an offer was made to prove that the principal was Wm. H. Kern, owner of the premises; that the lease had been made by W. R. Kern as his agent; that he had died after the demise and before the commencement of the action; and that the rent accruing after Ms death had been paid to Hood Gilpin and the Fidelity Trust Company, trustees under his will. Though not setting forth as particularly as might be done the right of Gilpin and the trust company, from probate of the will, and its provisions respecting the demised property, the offer was not objected to on this ground, and it may be implied from its language that they were authorized to receive the rent as trustees.
For the purposes of the case, it must be assumed that the matters set forth in the offer were facts. If they constituted a defense to the avowry, the right of the plaintiff to prove them cannot be doubted. The only question, therefore, is whether they form a defense to the avowant’s claim. Regarding the allegations embodied in or implied from the offer as true, they present a state of facts identical, in substance and effect, with those in Barrett v. Bemelmans. They show that .the real owner of the demised property was Wm. H. Kern; that W. R. Kern, by a lease in which he described himself as “ agent ” demised the premises to Bandel, the plaintiff, as agent for Wm. H. Kern; *393that between the demise and the commencement of the action Wm. H. Kern died; and that by his last will and testament Hood Gilpin and the Fidelity Trust Company were authorized to receive the rents accruing subsequent to his death.
Holding W. R. Kern to have made the demise as agent for Wm. H. Kern, the death of the latter was a revocation of the agency. The right of the agent to receive the rent thereupon ceased, unless preserved by some provision of the principal’s will. No such provision appearing, his authority as agent was at an end. It is not even material in whom the authority to receive the rent is now vested, since upon the death of the principal it passed out of the agent. As in Barrett v. Bemelmans, the revocation affected no interest of the agent, and the tenant, upon notice of it, was bound to recognize the right of the principal, or of the legal successors to that right.
The defense thus offered is in no sense a denial of the lessor’s title at the time of the demise. Admitting all that the lease imports, it is an averment that the lessor’s title has since determined, and that the right to receive the rent has passed to others. It falls within the well settled rule on this subject, illustrated in Newell v. Gibbs, supra, and the cases there cited.
It only remains to consider whether the defense set out in the offer is admissible under the pleadings. There being no general issue upon an avowry, matter of defense must be specially pleaded. It may be proper to observe, here, that the system of short pleadings that prevails in this state, however it may serve in other cases, is not to be commended in pleading to" an avowry; it is better and safer to plead, in extenso, the matter of defense.
The strictness formerly maintained in relation to pleading, has, in this state, become greatly relaxed. The reports abound in illustrations of a disregard of technicalities that stand in the way of substantial justice. One of the earliest is in Sauerman v. Weckerly, 17 S. & R. 116, where Mr. Chief Justice Gibson said: “An omission to compel the opposite party to perfect the pleadings beforehand ought to be considered, what it is in justice and truth, a tacit agreement to waive matters of form and try the cause on its merits; just as going to trial on a short plea is, according to our practice, a waiver of the right to demand a plea in full form.” The principle here laid down has become *394familiar in practice, owing to the too frequent inattention, on the part of counsel, to the rules of pleading. In general it maybe said that when a “ short plea ” is incomplete, or inadequate merely in form, it may be construed to embrace such matters, germane to the' issue it is designed to raise, as may reasonably be implied from it.
In the case before us, -if the question could be regarded as open, much might be urged in support of the view contended for by the appellant, that the plea of “ no rent in arrear ” may be sustained by proof that the rent had been paid to the persons by law entitled to receive it, and hence that nothing remained-in arrear. But the scope of the plea as defined by the courts does not permit this: Hill v. Miller, 5 S. & R. 355 ; Williams v. Smith, 10 S. & R. 202. The plea in full 'form is “ that no part of the said supposed rent, in the said avowry mentioned, was or is in arrear from the plaintiff to the defendant in manner and form as the defendant hath in his avowry in that behalf alleged.” It must be sustained by proof that the plaintiff has paid to the avowant the rent claimed in the avowry; nob that the avowant has no right to receive it.
But the defense to the avowry does not rest on the plea of “ no rent in arrear.” The record shows also a plea of “ payment.” Though in this- form incomplete, as a plea to the avowry, it cannot be disregarded. As a “ short plea ” it has no place in this action, the fact of payment being included in the plea of “no rent in arrear; ” hence its meaning here cannot be limited to its scope as a plea in assumpsit. The avowant might have required the plaintiff to set forth at large the ground of defense which it was designed to embrace. His omission to do this is a waiver of exception to its form. It may fairly be understood as implying that payment of the rent claimed had been made to the party entitled by law to receive it, and to permit proof of this. Under the facts set forth in the offer, the avowant could receive it only as agent for Wm. H. Kern’s successors in title, and for transmission to them. Their right is paramount to his, and payment to them must be regarded, in substance and effect, as a payment in discharge of the tenant’s obligation. In several English cases it has been held that payment to a person having a claim paramount to that of the avow-ant may be shown under the plea of “ no rent in arrear: ” *395.Jackson and Gross on Landlord and Tenant, 461, 462. With still greater reason may such a payment be shown under the plea of payment. It is further to be observed that there was no objection to the plaintiff’s offer on the ground that the matters embraced in it were not admissible under the pleadings. Had such an objection been made, it could have been met by an amendment under which no question could have arisen respecting the competency of the evidence offered. In general, as has frequently been held, a fault of pleading ivhich is amendable will be regarded as amended, when necessary to preserve an obvious right. If it be true that the plaintiff has in fact paid the rent for which this distress was made to those lawfully entitled to receive it, it would be a gross wrong, when not essential, to so closely adhere to form as to compel its payment a second time, without possibility of redress. Extreme technicality in pleading must be subordinated to the higher demands of justice.
The judgment is reversed, and a venire facias de novo awarded.
