The ruling invokes a law from 1864, a half century before Arizona became a state and women gained the right to vote.

"So this is a law that bans all abortions, there are no exceptions for health, for rape or incest, and it criminalizes abortion providers like myself."

Dr. Atsuko Koyama spoke to Reuters on Wednesday at Camelback Family Planning in Phoenix.

"Women's lives are at risk and it is so, so depressing and it angers me. It makes me very sad for our patients who will not be able to access abortion."

Arizona's top court ruled 4-2 to throw out the state's 15-week abortion limit in favor of the Civil-war era statute.

Arizonans were split on the decision.

"So I recently heard about it, and I am a Catholic, so, I feel that it's a god-sent rule."

"It's just really outrage, disappointment, fear for the women in our state. If we can do it here, other states will think they can do it there as well."

States were given the go-ahead to adopt bans like this in 2022 after the conservative-majority U.S. Supreme Court overturned Roe v. Wade, a ruling that had made access to abortion a constitutional right nationwide.

Since the Supreme Court's decision, abortion rights measures have prevailed everywhere they have been on the ballot.

Though the future of her clinic remains uncertain, Koyama says she plans to continue to treat patients until it is no longer possible.

"Today and every day until we can, we will be providing abortion services, reproductive health services."

Democrats were quick to pin the blame for Tuesday's ruling on Republican Donald Trump, as the former president gears up for a rematch with Biden in November's general election.

Trump's three conservative appointees to the U.S. Supreme Court secured the majority needed to overturn Roe two years ago.

Trump sought to distance himself from the ruling on Wednesday.

He said the court had gone too far, while also defending the U.S. Supreme Court's reversal of Roe.

Strategists in both parties said the ruling would push moderate voters toward Democrats, and mobilize young voters and voters of color.

Arizona, a battleground state, is poised to play a key role in November's election.

Biden beat Trump there by less than 11,000 votes in 2020.
