Block on Trump's Asylum Ban Upheld by Supreme Court
As reported by the Register, Facebook's "Beacon" program, through which advertisers like Blockbuster send information about a customer's off-Facebook activity for posting on that customer's Facebook page, has drawn a firestorm of criticism.
In the Dallas lawsuit, the plaintiff sued Blockbuster for sending movie rental information which was posted on the plaintiff's Facebook page. The plaintiff alleged violation of the Video Privacy Protection Act, which forbids disclosure of personally identifiable rental information unless the customer gives specific consent in writing.
Valid agreements require "consideration" (something of value) from all parties. If one party can unilaterally control whether or not it will perform its part, that party's consideration can be found "illusory" and the contract invalid. According to Judge Lyne, Blockbuster's ability to change the agreement's terms anytime made Blockbuster's consideration illusory.
