We are known for making a mountain out of a molehill. If Senator Aquino would wish to take his oath of Office as President by declaring that he will faithfully execute the Office of President of the Philippines, and will to the best of his ability, preserve, protect and defend the Constitution, it does not matter if he takes that oath before a humble barangay official or before a Supreme Court jurist.
Taking his oath before this low-level public servant would avoid the pomp, galore and expense attendant to a public celebration where a full panoply of corrupt bureaucrats, influence peddlers, socialites and gate-crashing matrons would compete for the billing on this opulent stage. Let us do away with symbolism and leave the treasury some money on vital state functions.
Vice President Lyndon Johnson, with Jackie Kennedy at his side, is sworn in as president immediately after the assassination of John F. Kennedy in 1963. He took the oath of office as the 36th President, aboard the presidential jet, Air Force One, before Sarah T. Hughes, U.S. District Judge which also returned Kennedy’s body to Washington, D.C. Johnson’s presidency began with a flurry of legislative activity.
Chester Arthur, 21st President of the U.S. took his oath of Office on Sept. 20, 1881, at his home in Yew York before a Notary Public.
Here is a Wikipedia Entry on Presidential Oathtaking.
While the Constitution does not mandate that anyone in specific should administer the oath, the oath is typically administered by the Chief Justice, but sometimes by another federal or state judge (George Washington was first sworn in by Robert Livingston, the chancellor of the State of New York in 1789, while Calvin Coolidge was first sworn in by his father, a Justice of the Peace and a Vermont notary public in 1923). By convention, incoming Presidents raise their right hand and place the left on a Bible or other book while taking the oath of office.
William R. King is the only executive official sworn into office on foreign soil. By special act of Congress, he was allowed to take his oath of the office of the Vice President on March 24, 1853 in Cuba, where he had gone because of his poor health. He died 25 days later.
