Disclaimer
Disclaimers vary in terms of their uniformity. Some may vary depending on the specific context and parties involved, while other types of disclaimers may strictly adhere to a uniform and established set of formalities that are rarely or never modified, except under official authority. Some of these formal disclaimers are required pursuant to industry regulation, qualification for protection under a safe harbor, and other situations where the exact wording of a particular clause or document may be dispositive in the event of a legal dispute. (See e.g., Product liability, Toxicity Class, Rule against perpetuities, Public Health Cigarette Smoking Act).
