You win, Zuckerberg.

CANBERRA (Reuters) - The Supreme Court in Australia's capital Canberra has ruled that Facebook is a sufficient way of serving legal documents to defendants who cannot be found.

The case surrounded a couple who defaulted on a loan.

"We couldn't find the defendants personally after many attempts so we thought we would try and find them on Facebook," lawyer Mark McCormack said.

"We did a public search based on the email address we had and the defendants Facebook page appeared."

He said that was enough to convince the court, which found Facebook was a sufficient way of communicating legal papers when it is the plaintiff's responsibility to personally deliver documents.
