Court of Appeals of New York.
805 THIRD AVE. CO., Appellant,
v.
M.W. REALTY ASSOCIATES, Respondent, et al., Defendant.
March 31, 1983.
 Suit was brought seeking rescission of modified contract for sale of air 
rights, and related relief, on theory of economic duress.   The Supreme Court at 
Special Term, New York County, Andrew R. Tyler, J., granted buyer's motion for 
preliminary injunction against seller, though not against issuer of letter of 
credit, and denied seller's cross motion to dismiss, and seller appealed. The 
Supreme Court, Appellate Division, First Judicial Department, 87 A.D.2d 544, 448 
N.Y.S.2d 15, modified order by vacating preliminary injunction and granting 
cross motion to dismiss complaint, and affirmed, and buyer appealed. The Court 
of Appeals, Simons, J., held that:  (1) date on which construction of foundation 
started was the "Sales Closing Date" on which, under contract, buyer was 
required to perform preconditions for transfer of air rights under terms of 
contract, which was annexed to the complaint, and (2) since buyer failed to do 
so, seller did not have duty to perform, and buyer failed to state cause of 
action for economic duress.
 Appellate Division affirmed.

OPINION OF THE COURT
 SIMONS, Judge.
 In September, 1979 plaintiff, 805 Third Avenue Co., and defendant, M.W. Realty 
Associates, [FN*] two limited partnerships, entered into a contract for the sale 
by defendant of a portion of its air rights to plaintiff.   In July, 1980 the 
parties modified the contract and in May, 1981 plaintiff instituted this action 
charging defendant with economic duress in compelling execution of the 1980 
modification.   It seeks to rescind the modified contract, to recover 
compensatory and punitive damages, and to obtain other related relief.   After 
the action was commenced, plaintiff obtained preliminary injunctive relief from 
Special Term which maintained the status quo prior to trial.   At the same time 
defendant moved to dismiss the complaint for failure to state a cause of action 
(CPLR 3211, subd. [a], par. 7).   Special Term denied defendant's cross motion.   
On appeal, the Appellate Division modified Special Term's order by vacating the 
preliminary injunction and granting the cross motion to dismiss (87 A.D.2d 544).   
Plaintiff appeals from that order.   It contends that its complaint states a 
cause of action, that in effect the Appellate Division has held that it must 
plead performance of conditions precedent in the September contract contrary to 
CPLR 3015 and that the Appellate Division has improperly dismissed the complaint 
*450 and granted judgment against it without prior notice (see CPLR 3015;  
Rovello v. Orofino Realty Co., 40 N.Y.2d 633, 389 N.Y.S.2d 314, 357 N.E.2d 970).   
Defendant contends that the complaint must be judged by considering the terms of 
the 1979 contract annexed to it and that when that is done plaintiff's complaint 
fails as a matter of law.   We agree with defendant.
FN* Defendant Citibank, N.A., is named as a party only because it issued a 
letter of credit for the benefit of defendant M.W. Realty Associates.   It has 
not participated in this appeal.
 Briefly, it appears from the complaint that plaintiff is the ground lessee of 
the entire blockfront on Third Avenue between 49th and 50th Streets in New York 
City except for a two-story building on the northeast corner of 49th Street and 
Third Avenue which is owned by defendant.   Plaintiff desired to construct an 
office building on the site and in order to increase to 31 stories the lawful 
floor area permitted under the city's zoning laws, it agreed to ***780 **447 
purchase the air rights necessary for the additional stories from defendant for 
$1,900,000.   The details of the purchase were set forth in a contract dated 
September 18, 1979.   By its terms plaintiff agreed to deliver in escrow a cash 
down payment and a promissory note for the balance of the purchase price which 
was to be paid over eight years.   In turn defendant agreed to deliver in escrow 
a declaration of zoning lot restrictions and a single lot and easement agreement 
which would complete the transfer of the air rights.  The escrow deposits were 
to be exchanged on the "Sales Closing Date" set forth in the contract or earlier 
at plaintiff's election.   After the deliveries to the escrow agents were made, 
and relying on the agreement, plaintiff obtained from the city a permit 
authorizing it to commence construction of the building foundation only.   It 
thereafter commenced excavation and construction and let contracts for erection 
of the superstructure.   Plaintiff then alleges in its complaint that in May, 
1980 it demanded that defendant deliver the documents "as required" by the 
contract of September 18, 1979;  that defendant refused to do so unless 
plaintiff agreed to a modification of the September contract on terms more 
favorable to defendant; that defendant's refusal was "unconscionable" and 
"oppressive" and was done "maliciously" to apply economic duress to plaintiff 
because defendant knew that pursuant to the terms of the ground lease any delay 
in construction would cause serious and irreparable injury to plaintiff and its 
general partners;*451 that compelled by such wrongful acts of defendant and the 
economic duress resulting from its wrongful refusal to deliver the documents, 
plaintiff executed the modified contract of 1980 to its damage and defendant's 
benefit.
 [1][2] The theory on which plaintiff seeks recovery permits a complaining party 
to void a contract and recover damages when it establishes that it was compelled 
to agree to the contract terms because of a wrongful threat by the other party 
which precluded the exercise of its free will (Muller Constr. Co. v. New York 
Tel. Co., 40 N.Y.2d 955, 956, 390 N.Y.S.2d 817, 359 N.E.2d 328;  Austin 
Instrument v. Loral Corp., 29 N.Y.2d 124, 130, 324 N.Y.S.2d 22, 272 N.E.2d 533;  
Oleet v. Pennsylvania Exch. Bank, 285 App.Div. 411, 137 N.Y.S.2d 779).   The 
existence of economic duress is demonstrated by proof that one party to a 
contract has threatened to breach the agreement by withholding performance 
unless the other party agrees to some further demand (Austin Instrument v. Loral 
Corp., supra ).   Thus, if all we had before us was plaintiff's complaint we 
would reverse and deny defendant's motion to dismiss, for accepting the 
allegations of the complaint as true, as we must, it alleges a cause of action 
upon which plaintiff may recover.
 [3][4][5] But that is not all there is before us.   Plaintiff has annexed to 
its complaint the contract of September 18, 1979 and by doing so it has made the 
contract a part of its pleading for all purposes (CPLR 3014; see, also, Wernham 
v. Moore, 77 A.D.2d 262, 432 N.Y.S.2d 711). Interpretation of the contract is a 
legal matter for the court (West, Weir & Bartel v. Carter Paint Co., 25 N.Y.2d 
535, 540, 307 N.Y.S.2d 449, 255 N.E.2d 709;  Bethlehem Steel Co. v. Turner 
Constr. Co., 2 N.Y.2d 456, 459, 161 N.Y.S.2d 90, 141 N.E.2d 590), and its 
provisions establish the rights of the parties and prevail over conclusory 
allegations of the complaint (see Miglietta v. Kennecott Copper Corp., 25 A.D.2d 
57, 266 N.Y.S.2d 936; Metcalf v. Metcalf, 274 App.Div. 744, 87 N.Y.S.2d 122;  
Siegel, Practice Commentaries, McKinney's Cons.Laws of N.Y., Book 7B, CPLR 
C3014:9, p. 11;  3 Weinstein-Korn-Miller, N.Y.Civ.Prac., par. 3014.14).   Thus, 
we must determine defendant's obligation from the contract and if it does not 
appear from the pleading as a whole that defendant has wrongfully withheld its 
promised performance, the complaint must be dismissed.
 Under the terms of the contract of September, 1979 defendant's declaration and 
lot agreement were to be delivered *452 to plaintiff on the "Sales Closing 
Date".   Plaintiff was entitled to the document, however, only if plaintiff 
secured delivery to defendant of (a) the cash down payment and promissory ***781 
**448 note held in escrow, plus interest, (b) a letter of credit securing 
payment of the balance of the purchase price and (c) the architectural drawings 
filed with the authorities as proof that the final floor area did not exceed the 
area defendant agreed to convey.
 Plaintiff does not contend, nor has it pleaded, that it did any of these things 
although the contract expressly provides that defendant's delivery of the 
declaration and lot agreement is conditioned on plaintiff doing so. Rather, it 
contends that the "Sales Closing Date", the time set for its performance in the 
contract, had not occurred, that its failure to perform was defensive matter to 
be pleaded by defendant and that its performance was excused because of 
defendant's refusal to perform.
 [6][7] The contract defined the "Sales Closing Date" as "the date of issuance * 
* * by the Department of Buildings" of "a Building Permit for the Proposed 
Building."   Date of issuance, insofar as pertinent here, was defined as the 
earlier of the date on which plaintiff received authorization to begin or on 
which it actually did begin "excavation or any other construction activity 
(exclusive of demolition) for the Proposed Building" (emphasis added).   
Concededly, construction of the foundation started on December 4, 1979.   
Plaintiff pleads that it had started in its complaint.   The dispute between the 
parties is whether the foundation work was the start of construction of the 
"Proposed Building" within the terms of the contract. Plaintiff contends that it 
was not because on December 4, 1979 it had not received final approval for the 
31-story office building and therefore the only office building it could legally 
erect under the zoning ordinances could not exceed six stories.   Obviously, 
plaintiff had no intention of building a six- story building, however;  the 
construction undertaken was for erection of a 31- story building.   Lease 
arrangements had been negotiated with prospective tenants to occupy such a 
building and construction contracts had been let to build it.   As a matter of 
law, December 4, 1979 was the "Sales Closing Date", the date that plaintiff 
began "excavation or*453  any other construction activity * * * for the Proposed 
Building", and that was the date plaintiff was required to perform the 
preconditions for transfer of the air rights.   Since it did not, it has not 
pleaded an actionable wrong by defendant and it cannot claim its nonperformance 
is excused or is defensive matter.
 [8] In short, the contract does not establish that defendant had an absolute 
duty to perform, as plaintiff claims.   Since plaintiff was not entitled to 
performance, plaintiff has failed to state a cause of action for economic duress 
for a party cannot be guilty of economic duress for refusing to do that which it 
is not legally required to do.   Defendant's cross motion should be granted, 
therefore, because unlike those cases in which plaintiff's pleading is 
sufficient on its face, though his right to recover may be doubtful (see Rich v. 
Lefkovits, 56 N.Y.2d 276, 281, 452 N.Y.S.2d 1, 437 N.E.2d 260), this action is 
controlled by the contract annexed to the complaint.   There is no dispute about 
the facts, only a dispute of law concerning the interpretation of that 
instrument.   Having resolved that dispute in defendant's favor, we must affirm 
(see O'Hara v. Del Bello, 47 N.Y.2d 363, 368, 418 N.Y.S.2d 334, 391 N.E.2d 1311;  
see Guggenheimer v. Ginzburg, 43 N.Y.2d 268, 275, 401 N.Y.S.2d 182, 372 N.E.2d 
17;  supra; Muller Constr. Co. v. New York Tel. Co., 40 N.Y.2d 955, 390 N.Y.S.2d 
817, 359 N.E.2d 328, supra ).
 Accordingly, the order of the Appellate Division, 87 A.D.2d 544, 448 N.Y.S.2d 
15, should be affirmed.
 COOKE, C.J., and JASEN, JONES, WACHTLER, FUCHSBERG and MEYER, JJ., concur.
 Order affirmed, with costs.

Co., 40 N.Y.2d 955, 390 N.Y.S.2d 817, 359 N.E.2d 328, supra ).
 Accordingly, the order of the Appellate Division, 87 A.D.2d 544, 448 N.Y.S.2d 15, should be affirmed.

 COOKE, C.J., and JASEN, JONES, WACHTLER, FUCHSBERG and MEYER, JJ., concur.
 Order affirmed, with costs.
