Final answer:
The power to amend the Texas Appraiser Licensing and Certification Act is held by the state legislature, as they are the law-making branch under the separation of powers established by the Texas Government.
Step-by-step explanation:
In Texas, the power to amend the Texas Appraiser Licensing and Certification Act lies with the state legislature. The Texas Government operates under a constitution that divides the powers into three departments: legislative, executive and judicial. This separation of powers dictates that only the legislative branch has the authority to make changes to laws, including acts such as the Texas Appraiser Licensing and Certification Act.
The governor and various executive officials have varying duties, but they do not possess the power to amend legislative acts, and the Texas Appraiser Licensing and Certification Board, being a regulatory body, cannot alter legislation either. Instead, they operate under the laws as established and modified by the legislature.
