Final answer:
The 27th Amendment allows citizens to propose laws through a constitutional convention.
Step-by-step explanation:
The 27th Amendment of the United States Constitution allows citizens to suggest and propose laws. This amendment, ratified in 1992, states that if enough states (two-thirds) request a constitutional convention, Congress must convene one. During this convention, citizens can propose amendments to the Constitution. However, it is important to note that while citizens can propose laws, it is ultimately Congress that has the power to pass or reject them.
