If the contractual terms are uncertain or incomplete, the parties do not reach an agreement in the eyes of the law.  An agreement is not a contract and the inability to agree on key issues that may include price or security elements may lead to the failure of the entire contract. However, a court will endeavour to implement commercial contracts where possible by excluding an appropriate design of the contract.  In New South Wales, even if a contract is uncertain or incomplete, the contract may remain binding on the parties if a sufficiently secure and comprehensive clause requires the parties to submit to arbitration, negotiation or mediation.

Legislation on equality, equal pay, racial discrimination, discrimination on the basis of disability, etc., have limited the total freedom of treaties.  For example, the Civil Rights Act of 1964 limited private racial discrimination against African Americans.  At the beginning of the 20th century, the United States experienced the "Lochner era," when the U.S. Supreme Court cracked down on economic rules based on contractual freedom and due process; these decisions were eventually overturned and the Supreme Court established respect for legal statutes and regulations that restrict contractual freedom.
 The U.S. Constitution contains a contractual clause, but is interpreted as limiting the retroactive effect of contracts.  Online agreements must be legally binding in order to enforce rules, protect privacy, avoid liability and inform users of what awaits you.
