An Arkansas man is suing Microsoft for $500 billion after he tried to amend his Xbox Live contract with the company and was ignored when he asked for legal arbitration.

David Stebbins, who is representing himself in a federal court in Seattle, spends most of his filing explaining why the court is not allowed to nullify the $500 billion payment. Stebbins was a user of Xbox Live, and since such a contract is binding on both Microsoft and an Xbox Live user, Stebbins thought he would try something.

In May he “submitted a notice” to Microsoft that he was “unilaterally amending the terms of service,” and if Microsoft did not terminate his Xbox Live membership, such changes would take effect in 10 days. Redmond did not terminate his membership and therefore accepted the new contract through inaction, Stebbins said.

Stebbins say that companies often employ the same strategy with consumers. In May 18 he invited the company to arbitrate a legal dispute in which he claimed $500 billion in damages. He says that he included in his notice a “forfeit victory clause,” which stated that if Microsoft didn’t respond within 24 hours, Stebbins would automatically win.Microsoft did not answer and Stebbins claims that is game set and match.

Stebbins has filed more than a dozen legal claims within the past year including similar stunts related to contract arbitration.
