Treaty, International Law and Constitutional Right
📘 Treaty, International Law, and Constitutional Right
1. Treaty
Definition:
A treaty is a formal, written agreement between two or more sovereign states (or international organizations) that is governed by international law.
Characteristics:
Binding on the parties who sign and ratify it.
Can cover any subject: trade, peace, environment, human rights, etc.
Requires consent and ratification under domestic law to be effective.
Example:
The Paris Agreement on climate change.
The Geneva Conventions on humanitarian law.
Role:
Treaties create legal obligations between states on the international plane.
2. International Law
Definition:
International law is a set of rules, norms, and standards that govern the relations and dealings between states and other international actors.
Sources:
Treaties (written agreements).
Customary international law (practices accepted as law).
General principles of law.
Judicial decisions and scholarly writings.
Scope:
Regulates areas such as peace and security, human rights, trade, diplomacy, environment, war laws, etc.
Enforcement:
International law relies largely on consent and cooperation, with enforcement mechanisms such as the International Court of Justice (ICJ), sanctions, and diplomacy.
3. Constitutional Right
Definition:
A constitutional right is a right guaranteed and protected by a country’s constitution to individuals or groups within that country.
Nature:
Enforceable within the domestic legal system.
Protects citizens against state actions.
Examples: right to freedom of speech, right to equality, right to life.
Difference from International Law:
Constitutional rights apply within a sovereign state; international law governs relations between states.
