18 Pa.C.S. § 3922: Theft by deception.

(a) Offense defined.--A person is guilty of theft if he intentionally obtains or withholds property of another by deception. A person deceives if he intentionally:

(1) creates or reinforces a false impression, including false impressions as to law, value, intention or other state of mind; but deception as to a person's intention to perform a promise shall not be inferred from the fact alone that he did not subsequently perform the promise;

(2) prevents another from acquiring information which would affect his judgment of a transaction; or

(3) fails to correct a false impression which the deceiver previously created or reinforced, or which the deceiver knows to be influencing another to whom he stands in a fiduciary or confidential relationship.

(b) Exception.--The term "deceive" does not, however, include falsity as to matters having no pecuniary significance, or puffing by statements unlikely to deceive ordinary persons in the group addressed.
