tie somebody's hands
tie (one's) hands
1. Literally, to bind one at the hands, typically with rope or something similar. Tie his hands so he can't escape!
2. By extension, to prevent one from behaving or acting in a certain way. I really wish I could help you get a refund, but the company's strict returns policy has tied my hands. If the government would stop tying our hands with these burdensome regulations, our economy would actually have a chance to flourish for once!
