In May of 1948, Anderson Trading Corp., as seller, and Albrecht Chemical Co., Inc., as buyer, arranged over the telephone for the sale and purchase of 10,000 pounds of a certain dye. Thereafter, Albrecht sent the seller two “ purchase orders ”, each for 5,000 pounds of dye. In addition to describing the merchandise and specifying their quantity and price, each order bore on its face the notation “ SigN AND 0ns Copy por Our Records ”, and, on its reverse side, eleven separately numbered terms and conditions. One of these conditions provided for the arbitration of any controversy or claim that might arise between the parties (¶ 11), and another recited that the “ order and the terms and conditions thereof shall be deemed accepted ” by the seller if he should fail to advise the buyer to the contrary within ten days (¶ 9).
The seller neither signed nor returned the purchase orders. Instead, it sent its own memoranda of sale to the buyer, and in them made no reference to the buyer’s purchase order or to any provision of it. About ten days later, on May 21st, Albrecht purchased a further quantity of the dye; on this occasion, the only document issued was the seller’s memorandum of sale. During the course of the following month, Albrecht, complaining that the goods were defective, demanded that the matter be arbitrated as provided in its purchase order. Anderson refused to accede to the request, maintaining that it had never agreed to arbitrate.
The purchaser thereupon initiated the present proceeding. The court at Special Term, holding that the seller’s explicit consent to arbitrate was unnecessary in view of its failure *440 to indicate disagreement, directed arbitration, and tbe Appellate Division affirmed. We see no alternative but to reverse, for tbe seller never agreed or bound itself to arbitration.
In tbe first place, considering tbe affidavits are before us, it may be that a contract was consummated by telephone, and, if that is so, nothing more need be said. Clearly, such an oral contract could not have created a binding agreement to arbitrate future differences, even if tbe parties bad so intended. contract to arbitrate a controversy thereafter arising between tbe parties must ’ ’, tbe Civil Practice Act is explicit, “ be in writing ” (Civ. Prac. Act, § 1449).
We go further, however, and bold that, even if tbe terms of tbe agreement were not finally fixed by tbe oral communications over tbe telephone and remained open to further negotiation, tbe subsequent written exchanges did not commit tbe seller to arbitrate. Tbe buyer’s purchase order was at best merely an offer or a counteroffer, and its retention by tbe seller without objection may not be deemed ratification of, or acquiescence to, tbe terms wbicb it contained.
This follows from tbe settled rule that, where tbe recipient of an offer is under no duty to speak, silence, when not misleading, may not be translated into acceptance merely because tbe offer purports to attach that effect to it. (See Matter of Tanenbaum Textile Co. v. Schlanger, 287 N. Y. 400, 404; Poel v. Brunswick-Balke-Collender Co., 216 N. Y. 310, 318 et seq.; More v. New York Bowery Fire Ins. Co., 130 N. Y. 537, 545, 547; see, also, 1 Williston on Contracts [Rev. ed.], § 91, pp. 279-280; Restatement, Contracts, § 72 [1].) That fundamental principle we stated in tbe Tanenbaum case (supra), which also concerned tbe binding of an arbitration clause (287 N. Y. at p. 404): ‘“A party cannot be held to contract where there is no assent. Silence operates as an assent and creates an estoppel only when it has the - effect to mislead * * *. When a party is under a duty to speak, or when his failure to speak is inconsistent with honest dealings and misleads another, then bis silence may be deemed to be ”
It is to be observed that, in the cases wherein acceptance has been thrust upon a party as tbe result of bis silence, something more than here was present. For example, tbe parties may *441 nave been advised and warned by a previous course of dealings that inaction would be taken as assent (see Matter of Catz Amer. Sales Corp. [Holleb & Co.], 298 N. Y. 504, affg. 272 App. Div. 689; see, also, 1 Williston on Contracts, op. cit., § 91B; Restatement, Contracts, § 72 [1], subd. [c]), or, acting through a common agent, they may have impliedly authorized him to bind them without more to various provisions, including one on arbitration. (See Matter of Catz Amer. Sales Corp. [Holleb & Co.], supra.)
In the present case, there is no basis for finding that the seller had a duty to speak out and reject the arbitration clause in the buyer’s purchase order. Those orders were not issued by an agent acting for both parties; and obviously the seller’s silence could not have been misleading. Indeed, on each occasion, instead of heeding the direction to “ SigN AND RettjrN ” the order, the seller dispatched its own memorandum. In whatever light we view that document — as affirmation of an agreement closed'over the telephone, as an offer based upon previous negotiations, or as a counteroffer to the purchase order — it did not amount to acceptance of the arbitration provision. Implicit in the seller’s conduct in sending its own memorandum was notice that it did not accede to the buyer’s terms; no positive rejection was necessary to avoid them. In point of fact, there is strong indication that the buyer could not have harbored any expectation that arbitration had been assented to, for the third transaction, that of May 21st, was executed without any purchase order from the buyer and with no mention whatever of a provision to arbitrate.
In short, neither expressly nor impliedly, neither directly nor indirectly, did the parties ever discuss arbitration or bargain about it, and certainly they reached no agreement thereon. (See Matter of Kahn [Nat. City 284 N. Y. 515, 523; Matter of Bullard [Grace Co.], 240 N. Y. 388, 395.) The buyer’s only recourse for alleged breach is to the courts.
The orders appealed from should be reversed, and the petition dismissed, with costs in all courts.
Orders reversed, etc.
