What Are Checks and Balances and Are They Still Working?

The Founders were afraid of concentrated power. They had watched European monarchs govern without constraint, had experienced colonial governors who answered to no one local, and had read extensively about how republics historically collapsed into tyranny.

Their solution was not to trust good leaders. It was to design a system that didn't require them.

Checks and balances is the mechanism they built. Whether it is still functioning is the most important political question of 2026.

The Three-Branch Design

The Constitution distributes power across three branches, each with specific tools to limit the others.

Congress (Article I): Makes law, controls the federal budget, declares war, approves treaties, confirms executive appointments, and can remove the president and judges through impeachment. It is, constitutionally, the most powerful branch — the one that represents the people most directly.

The President (Article II): Executes law, commands the military, conducts foreign policy, nominates judges and cabinet officials, and can veto legislation. Powerful in action, constrained in legal authority.

The Courts (Article III): Interpret law, determine what the Constitution means, and can strike down legislation and executive actions that violate constitutional limits. Federal judges are appointed for life specifically to insulate them from political pressure.

Each branch has genuine power to constrain the others. The system works when each branch is willing to use its tools.

The Central Assumption the System Makes

Here is what the Founders did not fully account for: checks and balances assume that each branch wants to check the others.

When the legislative branch declines to use its oversight powers — because members of the president's party control Congress and don't want to embarrass their own president — the check doesn't function.

When courts decline to rule on "political questions" — using that doctrine to avoid confrontations with the executive — that check doesn't function.

When the executive uses emergency declarations, executive orders, and novel legal theories to act without legislative authorization, and Congress does nothing in response, the system depends entirely on the judiciary as the last line.

This is the situation in 2026. It is not the system failing in a technical sense — all three branches still exist. It is the system failing in a functional sense, because the willingness to exercise restraining power has degraded.

What Has Actually Changed

Congressional war powers: The last formal declaration of war was 1942. Since then, military action has been authorized through vague resolutions that have been stretched far beyond their original scope. Congress has not reasserted this authority despite ample opportunity.

The budget power: Emergency declarations allow presidents to redirect military funds for other purposes. Congress passed a law — the National Emergencies Act — that was supposed to allow termination of emergencies. The mechanism has not worked as designed.

The immunity ruling: In Trump v. United States (2024), the Supreme Court held that former presidents have presumptive immunity from criminal prosecution for official acts. The dissents from Justice Sotomayor and others argued explicitly that this ruling placed the president above the law in ways the Constitution never intended. The practical effect — that a president faces no criminal liability for actions taken in office — significantly alters the check that criminal law provides.

Appointment and removal power: Executive agencies that were designed to be independent — the Fed, the NLRB, the CFPB — are facing removal of their leaders, tested through litigation that may fundamentally alter their independence.

What "Working" Actually Looks Like

Checks and balances are not a switch that is either on or off. They are a set of relationships between institutions that strengthen or weaken based on political will.

The Constitution gives Congress enormous power to check the executive. That power only functions when Congress uses it. The same is true for the courts, which have broad authority but cannot enforce their own rulings — the executive branch does that.

The system the Founders designed was built on the assumption that institutional self-interest would motivate each branch to guard its prerogatives against the others. "Ambition must be made to counteract ambition," Madison wrote in Federalist 51.

When partisan loyalty replaces institutional loyalty — when members of Congress prioritize their president's success over their own branch's authority — the counteracting mechanism stops working.

That is the stress the system is under now. It is not a crisis with a clear resolution date. It is a structural erosion that accumulates over time, making each subsequent step toward concentrated power easier than the last.
