WASHINGTON _ Republicans and Democrats sharply disagreed on whether Judge Brett Kavanaugh should join the Supreme Court, but across party lines, most agreed on what his appointment means.
A Justice Kavanaugh will almost surely create a significantly more conservative majority on the Supreme Court and shift the law to the right on a wide front _ from abortion and affirmative action to environmental protection, gun rights, immigration, property rights and religion.
That effect will be seen soon in small cases, such as a dispute the justices heard Monday over the fate of a tiny endangered species of frog, as well as in larger constitutional conflicts about the limits of presidential power or the rights of individuals against the state.
The pace of change will depend largely on Chief Justice John G. Roberts Jr., who has talked about the importance of stability in the law and of preserving the perception that the court is not following a political agenda. The chief justice's desire to avoid abrupt change could affect how quickly the court moves, but probably not its direction.
For the last 30 years, the court's center has been defined by the views of two moderate Republicans: Justices Sandra Day O'Connor and Anthony M. Kennedy. They leaned to the right in cases involving business, crime, job discrimination or government power, but at times, they joined with the liberals.
Kennedy played the key role in recognizing gay rights, for example. And both were wary of pushing the law too far to the right. Most famously, they balked in 1992 when fellow conservatives tried to overturn the abortion right set forth in Roe vs. Wade.
In 2006, O'Connor retired and was replaced by a much more conservative jurist, Justice Samuel A. Alito Jr. Now, with the addition of Kavanaugh, the court will have five conservative Republican appointees and four liberal Democratic appointees _ and no apparent swing vote. Like Congress, the court may no longer have members who are inclined to cross the aisle on occasion.
In Kavanaugh's years on the United States Court of Appeals for the District of Columbia Circuit, he regularly took the most conservative position on three-judge panels and often set out his views in lengthy dissents. He did not play the role of the moderate who tried to find a middle position in hard cases.
And if he was a staunch conservative at the time of his nomination in July, the fierce partisan fight over his confirmation makes it even less likely he will play a moderating role on the court.
Undoubtedly, there will be cases, as there are in most terms, where the justices agree in unanimous rulings. Some veteran advocates expect the chief justice and his colleagues to try extra hard to reach agreement this term. But many of these consensus rulings arise in non-ideological areas such as patents, taxes, bankruptcy or legal procedures.
Kavanaugh will be joining a court where the ideological divide is on display most days.
Monday morning, for example, the eight justices heard their first argument of the new term; at issue was the reach of the Endangered Species Act.
Seeking to protect a frog that faced extinction in Mississippi, the U.S. Fish and Wildlife Service had deemed as "critical habitat" some forest land nearby in Louisiana that had small ponds. Weyerhaeuser Co., which owned or leased some of the land, sued, arguing that the endangered frogs did not live there now and the "critical habitat" designation caused the value of its land to drop by $32 million.
The court's liberals saw the environmental rule as reasonable. Justice Elena Kagan said the landowner was not required to do much, other than not cut down all the trees and drain the ponds. The conservatives saw an example of extreme over-regulation. Justice Alito said that if the government wanted to control use of the land, it ought to pay the company for it.
Their comments suggested the justices would split 4-4 on the outcome. They may try to fashion a narrow, compromise ruling. Or they may opt to have the case re-argued in a few months, so new Justice Kavanaugh can cast the deciding vote.
On Wednesday, the court heard a case about a burial plot on a Pennsylvania farm, a seemingly small dispute that in reality could have a big effect in California and elsewhere.
Rose Knick sued after her township told her she must permit visitors to cross her land to see the burial site. With the help of the Pacific Legal Foundation, based in Sacramento, she took her case to federal court and argued that the local regulation violated her rights under the Fifth Amendment, which says "private property shall (not) be taken for public use without just compensation."
In the lower courts, to no one's surprise, Knick lost. The Supreme Court had set a procedural rule in 1985 that said property owners must go first to state courts to challenge a land-use rule and to seek compensation. That rule barred Knick's suit in federal court, but property rights advocates want the rule overturned.
On Wednesday, an attorney from Pacific Legal, joined by a top Trump administration lawyer, urged the justices to allow property owners to skip over the state courts and go directly to federal court. Several of the court's conservatives have called for such a move. If they can form a majority with the addition of Kavanaugh, developers and property owners could go to federal court to challenge all manner of zoning and development restrictions.
In California, that likely would mean more challenges to the state's rules on development in the coastal zone.
Kavanaugh's arrival also likely will bolster the Trump administration in its effort to fend off at least three significant legal challenges that are winding their way to the Supreme Court.
One involves the president's decision to repeal the Obama-era order that shields the so-called Dreamers _ immigrants who arrived in the U.S. illegally as children. A second challenges the Commerce Department's decision to add a question on citizenship to the 2020 census, a move that California's lawyers say could lead to an undercount of the population. In the third case, lawyers for transgender members of the military, and other transgender people who want to enlist, are fighting the White House's order to sharply restrict their ability to serve.
In all three cases, lower-court judges have blocked the administration, at least temporarily, and Trump's lawyers are trying to get cases before the Supreme Court in this year's term.
For many pro-business conservatives, the most talked-about issue on the agenda for a more conservative court is reining in the "administrative state" and the regulations that arise from federal agencies. Progressives praise rules that protect the environment, consumers, workers and investors from corporations and Wall Street; conservatives complain about dense and costly rules that are handed down by unelected bureaucrats.

On the appeals court, Kavanaugh was a strong advocate for giving the president and judges more power to restrain government regulations.
For social conservatives, abortion and religious liberty remain the top issues. Within a year or so, the court is likely to face a decision on whether to overturn or scale back the right to abortion _ the question on which Justices O'Connor and Kennedy split with their more conservative colleagues.
In recent years, the justices dealt with several disputes over abortion. Those cases arose at a time when Justice Kennedy held the deciding vote. He made clear he would uphold limited regulation of the procedures, but not measures that blocked or outlawed abortions entirely.
Now, with Kennedy gone and Kavanaugh sitting as his replacement, antiabortion lawyers in conservative states will press to prohibit abortion. Those laws will almost surely be struck down by federal judges because they violate Roe vs. Wade. But the eventual appeal will then head to the Supreme Court, forcing the chief justice and his colleagues to confront the issue that has rallied conservatives since the 1980s and helped elevate them to the Supreme Court.
