Legal regulations refer to the rules and laws established by governments or regulatory bodies to govern and control various aspects of society and industry. These regulations are put in place to ensure fairness, safety, and compliance with ethical standards. In research, legal regulations often pertain to protocols for conducting experiments, protecting human subjects, handling data, and ensuring the ethical conduct of researchers. Failure to adhere to legal regulations can result in fines, legal action, or the termination of research projects. Researchers must carefully follow and understand legal regulations relevant to their field in order to conduct their work ethically and responsibly.
