"A Brilliant Legal Mind": Ketanji Brown is formally sworn in as a US Supreme Court Justice.

Ketanji Brown Jackson, the first black justice of the Supreme Court of the United States, was invested this Friday in a ceremony attended by the president, Joe Biden.

"She has a brilliant legal mind, she is extraordinarily qualified and today she is making history," the Democratic president said on Twitter, recalling that to date he has nominated 84 federal judges and that no group of judges has been "so diverse."

His inclusion in the highest court does not change the ideological composition of that institution, since with six conservative-leaning judges and three progressives, it is more inclined to the right than ever since the 1930s.

"It's a pleasure to give you a warm welcome," court president John Roberts told him.

Brown Jackson, 52, was sworn in on June 30,

just as the departure of his predecessor, Judge Stephen Breyer, who decided to retire, became effective.

With his election, Biden fulfilled his promise to nominate a black woman to serve on the court.

During the ceremony, Jackson followed the custom of all other new justices since 1972 and sat in the chair that belonged to John Marshall, who served as Chief Justice for 34 years in the early 19th century.

Marshall was also a slave owner, which lent special significance to having Jackson take his place.

Along with his new colleague, Justice Clarence Thomas, and the late Justice Thurgood Marshall, Jackson is the third black person to serve on the Supreme Court in its entire history.

Friday's ceremony included a reading of the commission that appointed Jackson to the court.

He also repeated the oath he took when he was formally inducted in June, just after Judge Stephen Breyer's retirement.

Breyer was in a courtroom that was packed with the likes of House Speaker Nancy Pelosi and former Speaker Paul Ryan, Jackson's relative by marriage.

Jackson's parents, daughters, brother and in-laws were in the front row.

After graduating 'cum laude' from Harvard University, Brown Jackson developed a varied career - he was even an assistant to Breyer - and from 2021 until this past June he was a judge on the Court of Appeals for the District of Columbia, considered the second highest court country and a platform to ascend to the Supreme Court.

The two years she spent as a public defender for the poor make her the first high court judge with that kind of experience in more than three decades.

"Her historic nomination is an important step forward toward making the Supreme Court more like the nation as a whole," the Senate Judiciary Committee said when she was nominated.
