# Political Science and Governance: Constitutional Design, Electoral Systems in Practice, Executives and Legislatures, Federalism, and Courts and Judicial Review

> **Part 3 of 6** of the *Political Science, Human Systems and Governance* reference (plugin `political-science-human-systems-governance`), covering §9–§13. Sibling skills: `polisci-what-the-field-establishes-power-the-state-and-theory` (§0–§4), `polisci-collective-action-commons-social-choice-and-voting` (§5–§8), `polisci-bureaucracy-parties-voter-behaviour-and-polarization` (§14–§18), `polisci-regimes-state-capacity-corruption-ir-and-field-problems` (§19–§25), `polisci-reference` (§26–§31). Section numbers are shared across the set; a reference written as §N → `skill` points into that sibling skill.

> **Currency:** The theory is stable. Two areas are live. See §26 → `polisci-reference` for current democracy measurement, and the scholarly dispute about whether those measurements are reliable.

> **⚠️ A note on how this document handles contested questions.** ⚠️ **Political science
> contains robust empirical findings, contested empirical findings, and normative
> disputes that evidence cannot settle. This document tries to say which is which** (§1 → `polisci-what-the-field-establishes-power-the-state-and-theory`),
> **and where a question is genuinely contested it presents the strongest version of more
> than one position rather than picking.** ⚠️ **Where I report a finding, I attribute it;
> where scholars disagree, I say so.**
>
> **Complements a civil/industrial engineering reference (institutions as accumulated
> failure logs), a pedagogy reference (evidence quality in social science), and an
> economics-adjacent treatment of collective action.**
>
> **⚠️ GOTCHA** boxes mark the results that are counterintuitive or routinely misstated.
>
> **The three ideas that organize this document:**
> 1. **⚠️ COLLECTIVE ACTION PROBLEMS are the discipline's deepest structure** (§5–§6 → `polisci-collective-action-commons-social-choice-and-voting`).
>    **Individually rational behaviour producing collectively bad outcomes explains
>    government, taxation, regulation, unions, cartels and treaties — and Ostrom's work
>    showed the standard remedies are not the only ones.**
> 2. **⚠️ INSTITUTIONS SHAPE BEHAVIOUR, and the effects are often perverse** (§9–§15 → `polisci-bureaucracy-parties-voter-behaviour-and-polarization`).
>    **Electoral rules, veto points and federal structures produce predictable
>    consequences that designers frequently did not intend.**
> 3. **⚠️ MEASUREMENT IS THE FIELD'S BINDING CONSTRAINT** (§25 → `polisci-regimes-state-capacity-corruption-ir-and-field-problems`, §26 → `polisci-reference`). **Most interesting
>    political concepts — democracy, power, legitimacy, polarization — are hard to measure,
>    and disputes that look substantive are often measurement disputes underneath.**

## §9. Constitutional Design

**⚠️ Constitutions do three things: constitute institutions, allocate powers, and entrench
constraints against ordinary majorities.**
**⚠️ Key choices**: ⚠️ **codified vs uncodified; rigid vs flexible amendment rules
(⚠️ a constitution too hard to amend gets changed by judicial reinterpretation instead);
enumerated rights and whether they're justiciable; emergency powers (⚠️ historically the
most abused provision in any constitution); and the vexed question of unamendable clauses.**
**⚠️ Separation of powers vs FUSION** — ⚠️ **and note that Westminster systems fuse
executive and legislature deliberately, which produces decisive government and weaker
legislative checks.**
**⚠️ Veto players theory (Tsebelis)** is one of the more useful generalizations: ⚠️ **the
more actors whose agreement is required, and the more ideologically distant they are, the
harder policy change becomes.** **⚠️ This is a trade-off, not a defect — stability and
adaptability pull against each other.**
**⚠️ Constitutional design in divided societies**: ⚠️ **CONSOCIATIONALISM (Lijphart —
grand coalitions, group autonomy, proportionality, mutual veto) versus CENTRIPETALISM
(Horowitz — electoral incentives for cross-group appeals).** **⚠️ Both have real cases and
real failures, and the dispute is unresolved.**

## §10. Electoral Systems in Practice

**⚠️ The consequences of the choices in §8 → `polisci-collective-action-commons-social-choice-and-voting`, empirically:**
⚠️ **PR systems produce more parties, more coalition governments, higher women's
representation on average, and broader ideological range; majoritarian systems produce
clearer accountability, more decisive government, and more disproportionality.**
**⚠️ District magnitude is the single most important variable** — ⚠️ **more seats per
district means more proportionality, regardless of formula.**
**⚠️ Thresholds** trade fragmentation against inclusion.
**⚠️ Which is BETTER is a normative question** (§1 → `polisci-what-the-field-establishes-power-the-state-and-theory`): ⚠️ **it depends whether you value
accountability and decisiveness or representativeness and inclusion, and reasonable people
weigh these differently.**

## §11. Executives and Legislatures

```
⚠️ PARLIAMENTARY  executive drawn from and accountable to the
   legislature; ⚠️ can be removed by confidence vote — flexible
⚠️ PRESIDENTIAL  ⚠️ separate origin and survival; fixed terms
⚠️ SEMI-PRESIDENTIAL  ⚠️ dual executive; cohabitation problems
```
> **⚠️ GOTCHA — LINZ'S "PERILS OF PRESIDENTIALISM" is influential and CONTESTED, and it is
> worth knowing both halves.** ⚠️ **Linz argued presidentialism is more prone to breakdown:
> dual democratic legitimacy creates irresolvable deadlock, fixed terms are rigid, and
> winner-take-all raises the stakes.**
> **⚠️ The counterarguments are substantive: the correlation may be confounded (⚠️ most
> presidential systems are in Latin America, sharing other risk factors), the United States
> is a long-lived counterexample, and later work argues the electoral and party system
> matters more than the executive type.** ⚠️ **Treat it as a live debate, not a settled
> result.**

**⚠️ Legislature functions**: **representation, legislation, oversight, budget, and
legitimation.**
**⚠️ Bicameralism** — ⚠️ **and the real question is whether the second chamber is
"congruent" (same basis of representation, adding delay) or "incongruent" (different
basis, adding a genuine veto player).**
**⚠️ Committee systems** distinguish strong legislatures from weak ones far more reliably
than formal powers do.

---

## §12. Federalism

**⚠️ Divided sovereignty by territory, and the design questions are: what's allocated to
whom, how fiscal resources are split, and who arbitrates.**
**⚠️ The standard arguments FOR**: ⚠️ **accommodating diversity, bringing government closer
to the governed, policy experimentation ("laboratories"), and an additional check on
central power.**
**⚠️ The standard arguments AGAINST**: ⚠️ **inequality between units, coordination failure
and races to the bottom, duplication, and — historically significant — federalism as a
device for entrenching local domination against national reform.**
**⚠️ FISCAL FEDERALISM is where it bites**: ⚠️ **vertical fiscal imbalance (the level that
spends is not the level that raises), equalization transfers, and the accountability
problem when responsibility is shared.**
**⚠️ Subsidiarity** as the organizing principle: ⚠️ **decide at the lowest level capable of
handling it — easy to state, contested in every application.**

---

## §13. Courts and Judicial Review

**⚠️ The COUNTER-MAJORITARIAN DIFFICULTY is the central problem**: ⚠️ **why should
unelected judges overturn the decisions of elected bodies?**
**⚠️ The main answers, presented as positions:**
```
⚠️ RIGHTS PROTECTION  some things should be beyond majority reach
⚠️ PRECOMMITMENT  the people bind themselves in advance,
   Ulysses-and-the-mast
⚠️ REPRESENTATION-REINFORCING (Ely)  ⚠️ courts should intervene
   where the democratic process itself is blocked
⚠️ POLITICAL CONSTITUTIONALISM  ⚠️ the objection: rights disputes
   are reasonable disagreements, and legislatures are the
   legitimate forum (Waldron). ⚠️ A serious position, not a
   fringe one
```
**⚠️ Institutional variants**: **strong-form review (US), weak-form or dialogue models
(⚠️ the Canadian notwithstanding clause, the UK declaration of incompatibility), and
centralized constitutional courts (the European model) versus diffuse review.**
**⚠️ Judicial independence** depends on appointment method, tenure, budget control and
compliance norms — ⚠️ **and court-packing, jurisdiction-stripping and non-compliance are
the standard levers used against it.**
**⚠️ Interpretive methods** (⚠️ textualism, originalism, purposive, living constitution)
⚠️ **are themselves contested along lines that track political disagreement, which is part
of why judicial appointments became politically salient.**
