The distinction between the two is not very clear;  Warranties are primarily considered contract-based lawsuits, while negligent or fraudulent misrepresentations are based on tort, but there is a confusing mix of jurisdiction in the United States.  In modern English law, sellers often avoid using the term „represents“ to avoid claims under the Misrepresentation Act of 1967, while in America, „warrants and representations“ are relatively common.  Some modern commentators suggest avoiding words and replacing „state“ or „agree,“ and some model forms do not use words;  However, others disagree.  In India, electronic contracting is subject to the Indian Contract Act (1872), which requires certain conditions to be met when formulating a valid contact. Relative knowledge of the parties may also be a factor, as in Bissett v. Wilkinson, where the court found no misrepresentation when a vendor stated that the farmland sold would carry 2,000 sheep if worked by a crew; the Buyer has been deemed sufficiently competent to accept or reject the Seller`s opinion. In the tradition of civil law, contract law is a branch of the law of obligations.  Nullity occurs when a contract is terminated by court order, when a public body has not complied with the requirements of public procurement law. This corrective measure was provided for in the Public Procurement (Amendments) Regulation 2009 (SI 2009/2992). .
