I want to know the answer to the following question:
Regualtions carry force of law when based on reasonable interpretation of what?
All the background I'm provided with is that "Often, Congress is simply too gridlocked to draft detailed statutes that explain how the agency should react to every possible situation, or Congress believes the agency's technical specialists are best equipped to deal with particular fact situations as they arise.". Is that enough to answer the question?
Answer: no
