WASHINGTON, Oct. 3 (Xinhua) -- Hundreds of U.S. law professors are signing an online letter addressed to the U.S. Senate claiming that President Donald Trump's Supreme Court nominee Brett Kavanaugh is disqualified from sitting on the nation's highest court.

So far more than 500 law professors from nearly 100 law schools across the country have signed the letter, according to a Huffington Post report, noting that eight of the signatures in the letter were from professors at Yale, where Kavanaugh obtained his law degree.

"We regret that we feel compelled to write to you to provide our views that at the Senate hearings on Thursday, September 27, 2018, the Honorable Brett Kavanaugh displayed a lack of judicial temperament that would be disqualifying for any court, and certainly for elevation to the highest court of this land," the letter reads.

Judicial temperament is one of the most important qualities of a judge. As the Congressional Research Service explains, to be a judge requires that an individual has a personality that is evenhanded, unbiased, impartial, courteous yet firm, and dedicated to a process, not a result, the letter says.

"Instead of trying to sort out with reason and care the allegations that were raised, Judge Kavanaugh responded in an intemperate, inflammatory, and partial manner, as he interrupted and, at times, was discourteous to questioners," the letter goes on.

The letter will be available for more signatures through Thursday, when it will be presented to the Senate.

Earlier this week, the Harvard Law School informed the students that Kavanaugh will not teach his course as scheduled next semester. The judge has taught "The Supreme Court Since 2005" course at Harvard Law School since 2009.

Three women came forward last month to accuse Kavanaugh of sexual harassment or assault during his high school and college years. Trump on Friday ordered a one-week probe by the Federal Bureau of Investigation (FBI) into the allegations. Enditem
