Supreme Court

How Much Deference Does SCOTUS Owe to Congress?

Should it take more than a 5–4 vote for the Supreme Court to strike down a federal law?

In 1893, a Harvard law professor named James Bradley Thayer published one of the most influential articles in U.S. legal history. "The Origin and Scope of the American Doctraine of Constitutional Law" made a sweeping case for the doctrine of judicial deference, arguing that the U.S. Supreme Court was almost always out of bounds when it struck down an act of Congress for violating the Constitution. According to Thayer, a federal statute should only be invalidated on constitutional grounds in those extremely rare cases in which "those who have the right to make laws have not merely made a mistake, but have made a very clear one—so clear that it is not open to rational question."

Thayer understood that his approach, if faithfully adopted, would mostly eliminate the federal judiciary's ability to review federal laws on constitutional grounds. And he was just fine with that, since he thought federal judges should mostly butt out of such cases anyway, on account of the vast deference the judiciary owed "to the practical judgment of a legislative body."

This field is for validation purposes and should be left unchanged.

Thayer's hostility towards judicial review had a lasting influence on the thinking of several of the most important jurists of the Progressive and New Deal eras. "Both [Justice Oliver Wendell] Holmes and [Justice Louis] Brandeis influenced me in my constitutional outlook," Justice Felix Frankfurter declared in 1963. "But both of them derived theirs from the same source from which I derived mine, James Bradley Thayer."

I was reminded of Thayer's enduring influence the other day while reading a post by Jesse Wegman of the Brennan Center for Justice, which endorsed a version of Supreme Court "reform" that has been called a "consensus requirement." In essence, this requirement, which would be imposed on SCOTUS by Congress, would say that if the Court wanted to invalidate a congressional act, as Wegman put it, "it can't be by a one- or two-justice majority. It must be by a vote of 7–2, or 8–1, or even 9–0." According to Wegman, "the point of a consensus requirement is not to prevent the Court from deciding constitutional questions, but to make the justices work harder if they are going to strike down a law written and enacted by the people's elected representatives."

Thayer, writing in 1893, argued that SCOTUS should only strike down a congressional act when the constitutional violation "is so clear as to leave no room for reasonable doubt." Imposing a supermajority requirement on SCOTUS would be one way to bring to life in our time Thayer's vision of such a supremely limited judiciary.

But is that kind of limited judiciary really what today's liberals and progressives want? Perhaps it is, given the current 6–3 line-up of Republican and Democratic appointees on the Court. It wasn't always so, of course. When the Supreme Court struck down a key provision of the Defense of Marriage Act in United States v. Windsor (2013), the 5–4 ruling was hailed as a landmark liberal victory, no supermajority required.

And what about judicial review of the executive? If it's a good idea to require a SCOTUS supermajority to overrule an act of Congress, should it also take a SCOTUS supermajority to overrule an act of the president, who is also elected by, and democratically accountable to, the people? It seems odd to think that the Supreme Court should have more power to check the constitutional missteps of one branch of government than it has to check the constitutional missteps of the other branch.

Judicial deference has always been an idea that made for strange political bedfellows. Thayer's first followers were basically all Progressives who opposed the "reactionary" judges who ruled against their agenda. But conservatives such as Robert Bork soon became ardent Thayer-ians, too. Not so long ago, in fact, conservatives were the ones doing the loudest complaining about an "anti-democratic" judiciary thwarting the will of the people. And Trump, of course, is still loudly voicing such complaints, including against his own SCOTUS appointees.

So who knows, maybe the Democrats will gain control of Congress later this year and then persuade President Donald Trump to sign a new law requiring a supermajority vote from the Supreme Court before any act of Congress or the president may be ruled unconstitutional. In other words, today's Thayer-ians might want to be more careful about what they wish for.

    Root is fine with single district court judges issuing blatant partisan judgements unmoored from any legal reasoning. He cheers them attempting to direct federal domestic and foreign policy. He also cheers any time the SC rules against Trump.
    It's pretty obvious that Root isn't bothered by split decisions from the court, but hates the majority positions of the current makeup.
    He covers the courts, but somehow avoids regularly addressing how retarded KBJ is.

        I'm not going to say it was a great article, but you should probably read past the headline before deciding what it says.

          Yes. But that would take time, effort, comprehension and intelligence. MasterThief failed all those subjects.

      Yet you keep coming back. Perhaps you should add a dollop of self-respect to your dinner plate and go elsewhere for news? Or maybe you're a closet masochist.

    The Media is blind to Democratic Radicalism:

    https://www.nationalreview.com/corner/the-media-remains-blind-to-democratic-radicalism/

    "...Gerstein simply cannot — or will not — contextualize these comments for his readers.

    Jackson, he notes, "did not mention any specific attacks on the judiciary."

    No. Well, she wouldn’t, would she? It’s appropriate for her to remain vague. But Gerstein is under no such obligation. He can list those “specific attacks.” He can discuss the politics around this area in as much detail as he likes. And yet, grasping around for potential candidates, he lands here — and only here:

    'Since the Supreme Court struck down a key aspect of President Donald Trump’s tariff policy earlier this year, Trump has unleashed an unusually caustic series of attacks on the three members of the court’s conservative majority who joined the liberal justices in the 6-3 ruling.

    Trump has also called for the impeachment of district court judges who have ruled against the administration on other issues, like deporting alleged gang members to a notorious anti-terrorism prison in El Salvador without due process. Those calls prompted Chief Justice John Roberts to declare publicly that he believes that judges should not face impeachment due to disagreement with their rulings.'

    All of this is true. Trump did do this, and it was disgraceful. I have no problem with Gerstein or anyone else calling it out — as I have, each time it’s happened. The problem is that this is all Gerstein can come up with as an example of the judiciary “being attacked and undermined.” That isn’t the start of the list, or a sampling of the list. That is the list. Donald Trump is where his examples begin and end. Which means that, on May 12, 2026, Gerstein searched for “specific attacks on the judiciary” — for examples, in his words, of “salvos that jeopardize its independence” — and, when his search was complete, he had found only those that had come from Donald Trump.

    That is incredible. It is astonishing. It defies belief. The last week in American politics — including while Gerstein was writing this piece and while Justice Jackson was talking yesterday — has been so thoroughly dominated by Democrats threatening to pack the United States Supreme Court, abolish the Virginia Supreme Court, and interfere with any other court that gets in their way that there has barely been room for any other news. And he can’t — or he won’t — see it."

    "In Virginia, meanwhile, the rhetoric has been even sharper. The lieutenant governor of the state, Ghazala Hashmi, has said that the state’s Supreme Court is engaged in an “assault on our democratic institutions,” while Virginia’s attorney general, Jay Jones, accused it of having “put politics over the rule of law,” fueled “growing fears across our nation about the state of our democracy,” and effected “a dangerous trend of tilting power away from the people.” Worse still, as the New York Times reported, Democrats at the federal level — including Jeffries, who will almost certainly be speaker of the House of Representatives next year — got together with Democrats in Virginia to discuss a bizarre plan to abolish the Virginia Supreme Court in retaliation against its decision:"

    'The most dramatic idea they discussed — which would involve an unusual gambit to replace the entire state Supreme Court, with a goal of reinstating their gerrymandered map — drew mixed reactions on the call, said the people, and it was not clear that it would even be viable, or palatable to Gov. Abigail Spanberger and Democrats in the Virginia General Assembly.'

    Or, apparently, to Josh Gerstein, to whom it was completely invisible, along with every single other thing that high-ranking members of the Democratic Party have said in the last few days. Somehow, Gerstein heard a member of the United States Supreme Court “defend the judicial system against salvos that jeopardize its independence,” and the only thing that he could think of was Trump. That’s telling, but it’s also pretty alarming as a harbinger of things to come."

    Pfft..... "Not so long ago, in fact, conservatives were the ones doing the loudest complaining about an 'anti-democratic' judiciary thwarting the will of the people."

    What are the odds on that ?"in fact"?. 1 in a Million?

    It's no secret [D]emon-craps has consistently tried to dismantle the Constitutional Judiciary under the flag of 'democracy'.

    Conservatives? I don't think so.
    That's just yet another case of Leftard "[WE] do" Self-Projection "so it's all [R]s fault."

  5. Quicktown Brix   2 months ago

    If anything, I'd argue the opposite, that a single or double minority can overturn a law given Congress' and the Executive's predilection for usurping and trampling the Constitution's powers and protections and the ridiculous number of laws and regulations.

    Much of what the feds are doing should be left to the states. The last thing we need is to make it harder to overturn federal laws.

    1. The Average Dude (Who's Smarter Than You)   2 months ago

      That would be nice. The idea of judicial "deference" has always been dangerously misguided, and sometimes with tragic results.

    2. DesigNate   2 months ago

      “Much of what the feds are doing should be left to the states. The last thing we need is to make it harder to overturn federal laws.”

      100% agree.

  6. MollyGodiva   2 months ago

    The only way to resolve this issue is to take politics out of SCOTUS. All SCOTUS nominations need to come from a non-partisan selection committee with explicit rules to reject any judge that has a history of partisanship.

    1. Squirrelloid   2 months ago

      Who defines partisanship? Is a judicial philosophy of originalism = partisanship? How about a judicial philosophy of living constitutionalism?

      1. MollyGodiva   2 months ago

        Partisanship is someone who has a history of influencing the political process. Someone who has partisan writings, or given partisan speeches.

        1. Bruce Hayden   2 months ago

          Partisan is in the eyes of the beholder.

          Used to be that the ABA was listened to in judicial nominations. They would rate nominees, and those recommendations would be considered by those confirming nominees. Or even influencing whomever was nominated. Then the ABA started giving unqualified ratings to highly qualified Republicans, to keep them off of higher courts, and giving passing grades to even marginally qualified Dems.

          Turns out that the ABA became representative of a narrow band of attorneys - mostly academics and members of big firms, which would pay their annual dues.

    2. JesseAz (RIP CK)   2 months ago

      Every non partisan org set up by democrats has been more partisan, not less. See redistricting commissions.

      Fuck off commie.

      1. MollyGodiva   2 months ago

        There is no redistricting commission that creates a map as bad as completely shutting out one party. Also there are only 7 states with redistricting commissions. None have them have produced a majorly gerrymandered map.

        MAGAs are the biggest lying shits on the planet.

        1. JesseAz (RIP CK)   2 months ago

          And yet we see molly here lie his commie ass off again. Washington state and Oregon dummy. Go look at their commission makeups. They added green party and "independents" who support dems as the non partisan members.

          Do you get paid by the lie?

    3. Mickey Rat   2 months ago

      And where exactly are these paragons of non-partisanship to be found to man this committee?

      This is always a "who watches the watchers" problem.

      Especially since the people raising the stink right about judicial "partisanship" are bitching about the courts holding to the meaning of the law and not letting their party do whatever it wants.

      1. MollyGodiva   2 months ago

        No one can honestly defend presidential criminal immunity as having any basis in the Constitution. It is also very hard to justify allowing partisan gerrymandering. That should have been an easy case.

  7. IceTrey   2 months ago

    Or we prohibit government coercion so only laws that are retaliatory in nature can exist thereby marking a bright line of what is constitutional and what isn't.

  8. Uomo Del Ghiaccio   2 months ago

    I've noticed as the two major political parties phase into and out of power that their positions also flip. The only true solution is to breakup the corrupt two party systems we have and with multiple parties. An honest analysis of the Democrat and Republican parties reveals both of the two parties that have internal factions that are opposed to each other. Not even slightly opposed, but gravely opposed to each other. We would be better off if the factions broke away from the Democrat and Republican parties.

    The current system, when you party is in power, you want to maximize your power and then gift this new power to the other party when you in-evidently lose power. This the very definition of stupidity.

    1. JesseAz (RIP CK)   2 months ago

      Because we dont see similar issues in Europe and canada?

      1. mad.casual   2 months ago

        Again, Duverger's "Law" was invented by a socialist who didn't consider Stalin to be particularly totalitarian and, even if he were, his purges were a good thing. It's like citing Charles Manson's recommendation to eradicate traditional marriage as a means to resolve domestic disputes.

  9. MWAocdoc   2 months ago

    "on account of the vast deference the judiciary owed "to the practical judgment of a legislative body.""

    Reading this unprepared literally made me blow milk out through my nose. Then I had to pick myself back up off the floor after straining something from laughing so hard! I hope James Bradley Thayer is roasting in hell for all eternity for that.

  10. MWAocdoc   2 months ago

    "Judicial deference has always been an idea that made for strange political bedfellows."

    That's because there is nothing like a fundamental legal principle anywhere close to this "idea" and never will be. Assuming that a law passed by Congress and signed into law is not unconstitutional, then and only then should the Judiciary attempt to apply the intent of that law to actual cases. The Supreme Court should have been actively seeking out new laws to strike down - there is, after all, a huge number of laws that are clearly unconstitutional on their faces to choose from. The should not be heading the other direction now - or ever!

  11. Think It Through   2 months ago

    I have the same concept but almost entirely opposite -- it should take a 9-0 or 8-1 vote to agree that the government can do something. If reasonable people (those on the Court) disagree, then the government shouldn't be allowed to do it.

  12. Agammamon   2 months ago

    >Should it take more than a 5–4 vote for the Supreme Court to strike down a federal law?

    If the law is illegal - then no. Why should Congress get deference the Executive does not?

  13. TangoDelta   2 months ago

    I'm here for it but apply it fully. Approval of any law would require a vote of at least 80 Senators and 348 Representatives. None of this 51 and 218 crap.

    I'm willing to allow Senators or Reps to be seated with at least 2/3 of the vote. No 2/3 vote winner, hold another election/primary with all new candidates, failed candidates can only run again in the election for the following term. Repeat until someone does get 2/3 of the vote or the arrival of the next term where past failures can try their luck again.

  14. AJinNJ   2 months ago

    Super-majority no. Increase the number of justices, yes.

    We need a constitutional amendment that requires the number of appellate court circuits to be equal to the number of the US population divided by 20,000,000; rounded to the nearest whole number (add one if the result is an even number). Currently that gets us 17. The number of Supreme Court justices would match the number of appellate circuits. Each seat on the Supreme Court would be tied to a particular appellate circuit, nominees for that Supreme Court seat must live in that appellate circuit; thus creating nomination districts.

    Justices on the Supreme Court would have 7 year terms. After their term the House of Representatives would hold a super majority (2/3rds) No Confidence vote. If it falls short of 2/3rds the justice serves another term, if it reaches 2/3rds the seat is vacated. Terms would be limited to a total of 4 (28 years) or age capped at 10 years below the current average life span (currently ~70, as the average life span is currently ~80). Vacated seats would temporarily (6 month cap) be filled by the Chief Justice of the appellate court of that circuit (double duty).

    Appellate and Trail Court justices would follow the same review process but their terms would be 9 years for Appeals and 12 years for Trail (district) court justices.

    The Chief Justices would be selected by a vote of the House of Representatives every other year, without concurrence from the Senate.

    To transition to that from what we have now, you add one justice to the Supreme Court every other year (meaning at most 2 seats per Presidential term) until you hit the required number (currently 17).

    1. AJinNJ   2 months ago

      One concern one might bring up is what about states that have more than 20,000,000 in population. We also need an amendment that prohibits any state from having a population larger than 12,000,000. If a state's population grows beyond that, it must be divided, and the new states automatically admitted to the union.

  15. MichaelMeehan   2 months ago

    SCOTUS is established by the Constitution, which grants the Congress ZERO authority over it. They are separate and co-equal branches of the Federal government. The Supreme Court would be well within their rights and bounds to absolutely ignore any Congressionally mandated requirement for "consensus" short of an actual Constitutional Amendment.
