To CJ Sereno: Why is the ‘natural-born’ qualification for the presidency an impossible condition?

When did our people elect you, Madame Chief Justice, to amend the Constitution?

It says simply and clearly in Sec. 2, Article VII of the Constitution : “No person may be elected president unless he is a natural- born citizen of the Philippines, a registered voter, able to read and write, at least forty years of age at the time of the election, and a resident of the Philippines for at least ten years immediately preceding such election.”
