Who is responsible for passing and amending the Home Improvement Law in Maryland?

The General Assembly is responsible for passing and amending the Home Improvement Law in Maryland because it is the state's legislative body comprised of two chambers: the House of Delegates and the Senate. This body is tasked with enacting laws, including those related to home improvement and contractor regulations. Legislators propose bills, debate their merits, and ultimately vote on them to determine if they will become law.

In contrast, while departments such as the Department of Labor may enforce the laws, they do not create or amend legislation. The Governor's Cabinet typically oversees the implementation of policies set forth by the General Assembly but doesn't have the authority to pass laws. Lastly, the State Supreme Court interprets laws and can rule on their constitutionality but does not create or amend them. Therefore, the role of lawmaking and amendment resides specifically within the General Assembly, making it the correct answer.
