Separation of Powers

Part of Institutional Design

Dividing governance authority among distinct bodies so that no single person or group controls all functions.

Why This Matters

Power concentrated in a single person or body is the most reliable predictor of governance failure. This is not because powerful individuals are necessarily corrupt — many begin with genuine commitment to the community good — but because the institutional incentives created by unchecked power predictably corrupt behavior over time. When one person makes decisions, enforces them, and interprets whether they have been followed correctly, that person faces no structural constraint on self-dealing.

Separation of powers is the structural solution. By dividing governance authority among distinct bodies with different compositions, different selection methods, and different responsibilities, it creates a system where the ambition of each body checks the ambition of others. No single faction can make, enforce, and interpret the law without the cooperation of others who may have different interests.

The most important separation is between those who make rules, those who administer them, and those who adjudicate disputes about their application. These three functions should not be concentrated in the same hands even in small communities with limited institutional capacity.

Rule-Making Authority

The legislative or rule-making function belongs to the body most broadly representative of the community — typically an assembly, council, or committee composed of representatives from different geographic areas or occupational groups. Broad representation is essential because rules that disproportionately benefit narrow groups will not be followed by those they disadvantage.

Rule-making bodies should operate by documented procedures — how proposals are introduced, deliberated, and adopted — and their decisions should be publicly recorded. The key constraint on the rule-making body is that it should not also be the enforcement body. Legislators who enforce their own rules have immediate incentives to make rules that benefit the enforcers.

The rule-making body’s decisions should be prospective (governing future behavior, not retroactively penalizing past actions), general (applying equally to all community members), and specific enough that those subject to them can understand what is required.

Executive and Administrative Functions

The executive function — implementing rules, administering programs, conducting foreign relations, commanding response to emergencies — requires decisiveness and coordination that deliberative bodies cannot efficiently provide. Executive authority is therefore typically concentrated in a smaller body or single position for operational efficiency.

But this concentration creates exactly the power-abuse risk that separation of powers is designed to prevent. The checks on executive authority are critically important: the executive must work within rules set by the legislative body, must report regularly to that body, must obtain legislative approval for significant new actions (especially those involving large resource expenditures), and must be removable by the legislative body or community for misconduct.

Emergency powers — authority to act quickly in crises without prior legislative approval — are necessary but dangerous. Well-designed emergency authority is narrowly defined, time-limited, requires notification of the legislative body, and is subject to post-crisis review.

Adjudicative Functions

The adjudicative function — determining whether rules have been violated, resolving disputes about their interpretation, and assigning consequences — must be independent of both the rule-making and administrative bodies. An executive that also adjudicates disputes in which it is a party will consistently rule in its own favor. A legislature that adjudicates rule violations has incentives to make rules broad enough to threaten anyone it dislikes.

Judicial independence has specific institutional requirements: judges should be selected through a process that does not give complete control to either the legislative or executive body; they should have protected tenure during good behavior; and their compensation should not be subject to reduction in retaliation for unpopular rulings.

In small communities with limited resources, full institutional separation may not be immediately achievable. A workable minimum: the same individuals who make and administer rules should not also adjudicate disputes arising from those rules. If there is only one governing council, it should at minimum form a distinct dispute-resolution panel whose members are selected differently and recuse themselves from cases involving their own previous decisions.

Checks and Balances

Separation of powers creates distinct bodies, but checks and balances are what give each body leverage over the others. Without mechanisms for one body to constrain another, separated powers simply produce conflict between co-equal fiefdoms.

Classic checks include: legislative approval required for major executive appointments; judicial review of whether legislative acts comply with the community’s foundational rules; executive enforcement required for judicial decisions to have effect; legislative power to remove executive officials for misconduct; and community power to replace legislative members through elections or recall.

What matters is not the specific institutional form but the underlying principle: no body should be able to act without accountability to any other body.

Practical Implementation in Small Communities

A community of fifty to three hundred people cannot maintain elaborate separate institutions. But it can establish functional separation through role distinctions within a smaller number of people. A council of seven might divide into a three-person administrative committee (executive), a two-person judicial panel (adjudicative), with all seven voting on new rules (legislative) — but members of the administrative committee recuse from judicial panel service, and no individual may serve both in administration and adjudication.

This modest separation — maintaining the principle even with minimal institutional elaboration — produces dramatically better governance outcomes than concentrating all three functions in whoever happens to be the most respected elder at any given moment. The principle matters more than the institutional architecture that implements it, and the principle can be implemented at any scale.
