This is just a contract question, and I am not concerned with the intellectual property implications at this point.
I'm in the US.
The scenario: Suppose I was given an unsolicited document, so at no point did I agree to receive it or any terms attached to it. The document expressly states, however, that I may not electronically reproduce or even print the document without the owner's prior consent. Although I did not agree to these terms on receipt, so there is no mutual assent there, is there any legal theory under which I could be bound by those restraints? E.g., if I print or email the document without the owner's consent could I be liable under the document's terms (similar to a click-wrap or browse-wrap)?
