President Donald Trump’s dramatic assault on heretofore seemingly impregnable citadels of federal power has understandably energized the conservative movement. President Ronald Reagan eloquently set forth the case for returning to a constitutional republic dedicated to the protection of individual liberty. The Trump administration appears determined to put that philosophy into practice.

However, the administration is running into predictable resistance, focused on the courts. And the response has been disturbing, if understandable. Elon Musk angrily complained: “A corrupt judge protecting corruption. He needs to be impeached NOW.” Vice President JD Vance was more measured in tone but more extreme in practice: “If a judge tried to tell a general how to conduct a military operation, that would be illegal. If a judge tried to command the attorney general in how to use her discretion as a prosecutor, that’s also illegal. Judges aren’t allowed to control the executive’s legitimate power.” The president’s deputy chief of staff, Stephen Miller, sounded like just another leftist when he trashed one judicial decision as “an assault on the very idea of democracy itself.” There’s little doubt that many MAGA supporters would like the president to ignore adverse legal rulings. As President Andrew Jackson declared a couple centuries ago, announcing: Supreme Court Chief Justice “John Marshall has made his decision; now let him enforce it.”

Yet only a couple months ago, Republican senators were battling against lame-duck approval of the last Biden judicial appointments because responsible jurists are necessary to uphold the rule of law. (Biden actually ended up winning approval of two more federal judicial appointments than Trump, but the latter triumphed in the Supreme Court category 3–1.) And just a few months ago, back when Democrats still claimed that Joe Biden was energetically carrying out his presidential duties, his administration, under pressure from the Left, released a blueprint for judicial reform. Surprisingly, given his general surrender of domestic policy to progressives, the proposal was modest and left the judiciary intact.

This did not satisfy lefties who were angry that judges were upholding the law — for instance, blocking the president’s attempt to buy votes by turning student debt over to the taxpayers. Progressives determined to use the courts to make, rather than enforce, law were apoplectic when the Supreme Court returned to reading, rather than rewriting, the Constitution, as when it overturned Roe v. Wade. Those who believed courts are to act as continuing constitutional conventions with the duty to steadily expand state power proposed a range of radical “disempowering reforms,” and, most importantly, court packing, simply adding judges and turning the courts into unelected legislative bodies. Conservatives led the fight against such measures, as they did nearly a century ago when President Franklin Delano Roosevelt pushed such a scheme, which failed to pass but appeared to trigger a Supreme Court retreat, the infamous “switch in time that saved nine.”

Although conservatives today are frustrated by judicial barriers to radical change, the Founders intended that Congress reign supreme. They were adamant that the newly liberated colonies were not going to replicate the British monarchy with a permanent and powerful president. And political experience around the world, including in the U.S., has demonstrated the danger of overweening executive power, vindicating the Constitution’s framers.

Particularly important in recent years, the courts have become a vital redoubt for free speech and especially religious liberty. Democrats once stood with Republicans in defense of faith. For instance, Congress overwhelmingly approved the Religious Freedom Restoration Act in 1993. Indeed, the legislation was sponsored by Sen. Chuck Schumer. However, it turned out that the Left’s backing for freedom of religious conscience only extended to quaint faiths, such as the Amish and Native Americans. When others, most notably orthodox Christians, opposed the Left’s planned social revolution, many Democrats decided that the state should crush opposition and force the recalcitrant into line. For instance, if even one photographer refused to cover or baker refused to bake a cake for a gay wedding, it apparently was seen as the end of the progressive dream.

Into the breach stepped the courts. Not always consistently and often reluctantly, they generally blocked left-wing attempts to privatize faith, allowing people to believe what they wanted, but unable to act on those beliefs in any meaningful way. This goes back well before Trump systematically sought to fill the judiciary with appointees who believed in the rule of, not by, law. One of the most important decision was Hosanna-Tabor Lutheran Church and School v. Equal Employment Opportunity Commission. In 2012, an unanimous high court blocked the Obama administration from forbidding religious schools from making faith a requirement for employment.

Chief Justice John Roberts wrote the court opinion in which the justices declared:

The EEOC and Perich contend that religious organizations can defend against employment discrimination claims by invoking their First Amendment right to freedom of association. They thus see no need — and no basis — for a special rule for ministers grounded in the Religion Clauses themselves. Their position, however, is hard to square with the text of the First Amendment itself, which gives special solicitude to the rights of religious organizations. The Court cannot accept the remarkable view that the Religion Clauses have nothing to say about a religious organization’s freedom to select its own ministers.

Not all religious decisions are unanimous, expansive, or definitive. But the Constitution, and the willingness of jurists, including traditional liberals, to enforce the First Amendment, has protected people of faith from America’s founding through today. What if Vice President and later President Biden had announced that those administrations were not going to allow unelected judges to undermine democracy by thwarting legitimate and democratic policy choices made by the nation’s top elected leaders? And they had ignored courts that halted Democratic abuses?

It would be particularly ironic for conservatives to join the Left in seeking to diminish the courts at a time when a Republican president and Senate are poised to continue conservative efforts to return judges to the job of judging, not legislating. Especially with the support of what appears to be a solid moderate-conservative Supreme Court majority. An unhappy Adam Serwer from the Atlantic acknowledged: “The current makeup of the Roberts Court is itself the outcome of a partisan battle that has spanned decades, one in which the conservative legal movement has won a tremendous victory that is certain to shape American life for generations to come.”

Republicans today might dream of following four years of President Trump with eight years of President Vance, but they could be forced to rely on the courts to stop Democratic initiatives sooner than they expect. After all, on Jan. 20, 2017, Democrats were expecting to be in charge for a long time, and even most Republicans believed that Trump was finished. Today it is the Democrats who are in disarray. No one knows the next radical and unexpected turn in American politics.

Rather than attacking the courts, conservatives should develop their own reform agenda. A code of conduct would help protect the judiciary’s reputation. Fixed terms and term limits would broaden representation on the courts. And easing the constitutional amendment process would reduce pressure on judges to act like politicians.

It’s understandable why many conservatives are cheering the administration in its efforts to dismantle the deep state gone wild. And they should fight in court against judges who overstep proper legal authority. After all, that is one advantage of now having a Supreme Court that better respects the rule of law. However, when Lord Acton warned us that “power tends to corrupt, and absolute power corrupts absolutely,” he didn’t exempt the good guys. Warns Ilya Somin of George Mason University Law School: “The new Trump administration may be heading in the direction of disobeying court orders that go against it. If they do so and get away with it, there are likely to be dire consequences for our constitutional system. An administration not bound by court orders is ultimately not bound by the Constitution and the laws, either.”

And that would be bad for all of us. The judiciary has an essential role to play in sustaining the American republic. Ironically, it was the same Andrew Jackson who insisted that “All the rights secured to the citizens under the Constitution are worth nothing, and a mere bubble, except guaranteed to them by an independent and virtuous Judiciary.” That was true two centuries ago. It remains the case today.
