Harvard may ignore early decision college application results and enroll students who have in theory already committed to other schools. On one hand, this does encourage applicants to break their (non-binding) promises to other schools and is very close to tortious interference with a contract. On the other hand, these are not legally binding contracts and hence Harvard is not required to refrain from offering them a spot even after they've supposedly "committed" to another Ivy League school. Given the current problems with early decision programs (also discussed here), this could be a very interesting development. (Via Metafilter.)
