With the passing of Justice Antonin Scalia, there is now a vacancy that must be filled on the Supreme Court — and President Obama has a Constitutional responsibility to nominate someone to take his place.

The Supreme Court is a vital institution of American democracy and, since the founding of our country, the President of the United States has had the responsibility to appoint a Justice to the Supreme Court every time — and any time — there is a vacancy on the bench. It then falls to the United States Senate to confirm that nominee before he or she can take her seat on our nation’s highest court.

As President Obama said, “The Constitution is pretty clear about what’s supposed to happen now.”

The confirmation of a Supreme Court Justice is a solemn responsibility that the President and the Senate share under the U.S. Constitution. It is not a political opportunity that reflects “left” or “right,” Democrat or Republican. It’s a serious obligation to make sure that an indisputably qualified person of integrity is nominated and confirmed to sit on the highest court in the land.

The President plans to offer his nominee for the Supreme Court to the Senate — and the Senate has more than enough time to confirm that nominee.

Here are the facts:

FACT: Six Justices have been confirmed in a presidential election year since 1900.

For more than two centuries, it has been standard practice for Congress to confirm a president’s Supreme Court nominee, whether in a presidential election year or not. Of the six justices confirmed since 1900, three have been Republicans. The most recent Justice to be confirmed in an election year was Justice Kennedy — appointed by President Reagan — who was confirmed by a Democratic-controlled Congress in February of 1988.

FACT: Every nominee has received a vote within 125 days of nomination.

Since 1975, the average time from nomination to confirmation is 67 days. In fact, since 1875, every nominee has received a hearing or a vote. The longest time before confirmation in the past three decades was 99 days, for Justice Thomas, and the last four Justices, spanning two Administrations, were confirmed in an average of 75 days.

The Senate has almost a full year — more than 300 days — to consider and confirm a nominee.

FACT: It will be harmful and create unsustainable uncertainty if Congress fails to act on the President’s nominee.

The Supreme Court could go the better part of two Terms with a vacancy if the Senate rejects its Constitutional responsibility. It’d be unprecedented for the Court to go that long with an empty seat. Here’s why it’s harmful:

The Court’s 4-4 decisions have no value in establishing precedent on which future decisions can rely. They also cannot establish uniform nationwide rules. That means if multiple courts ruled differently on an issue before it arose at the Supreme Court, a 4-4 ruling would leave those different rules in place in different states. The result is an unsustainable uncertainty — for the law, for individual liberties, and for our economy.
