Laws that protect individuals or groups from bias and discrimination on the basis of factors such as age, sex, religion, national origin or disability. Anti discrimination laws may be imposed on the local (e.g. City, county), state or federal level. Federal laws prohibit discrimination in any place of public accommodation. Anti-discrimination provisions are sometimes included in contracts to allow a party to the contract to cancel without liability in the event the other party or parties is found guilty of engaging in discriminatory practices.
