Kurdish Policy Analysis

Despite formal separation of powers, Iran’s political system remains tightly centered on the Supreme Leader, with elected institutions operating under clerical oversight.

Kurdish Policy Analysis / SULAIMANI, April 18— Since the Iranian Revolution, Iran has evolved into a political system that blends republican institutions with strong clerical oversight. While the constitution establishes three branches of government—legislative, executive, and judicial—all operate under the supervision of the Supreme Leader, currently Ali Khamenei.

On paper, Iran resembles a structured constitutional system. In practice, however, its political architecture is highly centralized, with key decision-making authority concentrated at the top of the clerical hierarchy.

A dual system: elections within limits

Iran’s political model combines electoral mechanisms with extensive vetting and oversight. Citizens vote for parliament and the presidency, but candidates must first pass ideological screening by unelected bodies aligned with the Supreme Leader.

This system produces a hybrid structure: competitive elections exist, but within a tightly controlled political field.

Legislative power: Three councils, limited independence

Iran’s legislative authority is not concentrated in a single institution. Instead, it is distributed across three interconnected bodies.

1. Parliament (Majles)

The Islamic Consultative Assembly is elected every four years and consists of 290 members.

It is responsible for:

• Drafting and passing laws
• Approving national budgets and international agreements
• Questioning or impeaching ministers and the president

However, parliamentary authority is constrained by a higher review body that can veto its decisions.

2. Guardian Council: the gatekeeper of politics

The Guardian Council is one of the most powerful institutions in the system. It consists of 12 members—six clerics appointed directly by the Supreme Leader and six jurists indirectly influenced through the judiciary.

Its authority includes:

• Vetting all election candidates
• Blocking or approving parliamentary legislation
• Interpreting constitutional compliance with Islamic law

In effect, the council determines who is allowed to participate in Iran’s political system, making it a decisive filter in both legislative and presidential elections.

3. Expediency Council: the arbitration body

The Expediency Discernment Council acts as a mediator between Parliament and the Guardian Council when disputes arise.

Beyond arbitration, it also serves as an advisory institution to the Supreme Leader, offering strategic guidance on governance and policy.

Although formally positioned as an independent arbiter, its membership is directly appointed by the Supreme Leader, reinforcing executive dominance over legislative disputes.

Executive branch: The president within constraints

Iran’s president is elected by popular vote and serves as the head of government. However, the role is structurally limited.

The president is responsible for:

• Managing the cabinet and state administration
• Proposing ministers for parliamentary approval
• Implementing domestic policy

But key areas—security, military affairs, and strategic foreign policy—lie outside presidential authority.

A major coordinating body, the Supreme National Security Council, brings together senior officials including the president, military commanders, and intelligence chiefs. Yet even this council operates under guidelines set by the Supreme Leader.

As a result, the presidency functions more as an administrative executive than a fully sovereign political office.

Judiciary: institution under clerical appointment

Iran’s judiciary is headed by a chief appointed directly by the Supreme Leader. This official oversees the entire legal system, including court administration and judicial appointments.

Key institutions include the Supreme Court of Iran and the office of the prosecutor general.

The judiciary is responsible for:

• Interpreting and enforcing laws
• Supervising lower courts
• Appointing judges nationwide

However, because its leadership is appointed from above rather than independently selected, the judiciary operates within the ideological framework of the Islamic Republic rather than as a separate power center.

The Supreme Leader: central node of authority

At the core of Iran’s political system is the doctrine of Velayat-e Faqih, which establishes clerical guardianship over the state.

The Supreme Leader holds authority over:

• Armed forces and military strategy
• Intelligence and internal security
• Foreign policy direction
• Appointment of key judicial and political figures
• Oversight of major institutions such as the Guardian Council and state media

This position transforms the Supreme Leader into the ultimate arbiter of political and constitutional authority.

Assembly of Experts: oversight in theory, continuity in practice

The Assembly of Experts is officially responsible for appointing, supervising, and potentially removing the Supreme Leader. It consists of 88 clerics elected every eight years.

However, candidates for the Assembly must themselves be approved by the Guardian Council, creating a circular vetting structure.

In practice, the body has never challenged the authority of the Supreme Leader, functioning more as a legitimizing institution than an active supervisory force.

A system of controlled balance

Iran’s political structure is often described as a system of “checks and balances,” but the balance is asymmetrical.

While institutions exist for legislation, governance, and judicial oversight, they all operate within boundaries defined by clerical authority. The result is not a separation of powers in the Western sense, but a hierarchy of powers centered on a single office.

Conclusion: centralized pluralism

Iran’s governance model combines republican elements—elections, a parliament, and a presidency—with a parallel clerical structure that overrides or supervises all branches.

This arrangement has allowed the Islamic Republic to maintain institutional continuity for more than four decades, but it also concentrates ultimate authority in the hands of the Supreme Leader, making Iran’s political system highly centralized despite its formal complexity.

In essence, Iran operates as a managed political system where plural institutions exist, but sovereignty remains vertically anchored at the top of the clerical state.
