The legal issues of Burger King include several legal disputes and lawsuits involving the international fast food restaurant chain Burger King (BK) as both plaintiff and defendant in the years since its founding in 1954. These have involved almost every aspect of the company's operations. Depending on the ownership and executive staff at the time of these incidents, the company's responses to these challenges have ranged from a conciliatory dialog with its critics and litigants to a more aggressive opposition with questionable tactics and negative consequences. The company's response to these various issues has drawn praise, scorn, and accusations of political appeasement from different parties over the years.

A diverse range of groups have raised issues, such as People for the Ethical Treatment of Animals (PETA), over the welfare of animals, governmental and social agencies over health issues and compliance with nutritional labeling laws, and unions and trade groups over labor relations and laws. These situations have touched on the concepts of animal rights, corporate responsibility and ethics, as well as social justice. While the majority of the disputes did not result in lawsuits, in many of the cases the situations raised legal questions, dealt with statutory compliance, or resulted in legal remedies such as changes in contractual procedure or binding agreements between parties. The resolutions to these legal matters have often altered the way the company interacts and negotiates contracts with its suppliers and franchisees or how it does business with the public.

Further controversies have occurred because of the company's involvement in the Middle East. The opening of a Burger King location in the Israeli-occupied territories led to a breach of contract dispute between Burger King and its Israeli franchise; the dispute eventually erupted into a geopolitical conflagration involving Muslim and Jewish groups on multiple continents over the application of and adherence to international law. The case eventually elicited reactions from the members of the 22-nation Arab League; the Islamic countries within the League made a joint threat to the company of legal sanctions including the revocation of Burger King's business licenses within the member states' territories. A second issue involving members of the Islamic faith over the interpretation of the Muslim version of Canon Law, Shariah, regarding the promotional artwork on a dessert package in the United Kingdom raised issues of cultural sensitivity, and, with the former example, posed a larger question about the lengths to which companies must go to ensure the smooth operation of their businesses in the communities they serve.

A trademark dispute involving the owners of the identically named Burger King in Mattoon, Illinois led to a federal lawsuit; the case's outcome helped define the scope of the Lanham act and trademark law in the United States. An existing trademark held by a shop of the same name in South Australia forced the company to change its name in Australia, while another state trademark in Texas forced the company to abandon its signature product, the Whopper, in several counties around San Antonio. The company was only able to enter northern Alberta, in Canada, in 1995, after it paid the founders of another chain named Burger King.

Legal decisions from other suits have set contractual law precedents in regards to long-arm statutes, the limitations of franchise agreements, and ethical business practices; many of these decisions have helped define general business dealings that continue to shape the entire marketplace.

Legal disputes and agreements

Animal welfare

In 2001, the animal rights group PETA began targeting fast food chains in the United States regarding the treatment of chickens by suppliers such as Tyson Foods. Using parodies of corporate logos and slogans, the group sought to publicly embarrass the companies into changing their corporate policies in dealing with their poultry suppliers. After winning concessions from McDonald's with its "McCruelty" campaign, the group targeted Burger King with a six-month campaign it called Murder King. The group and its supporters, with the backing of celebrities including Alec Baldwin, James Cromwell, and Richard Pryor, staged protests outside Burger King restaurants across the United States, calling on the company to establish these new compliance guidelines. On June 28, 2001, Burger King entered into an agreement with the group and established a contractual framework that defined procedures to ensure that its suppliers were conforming to the agreed-upon standards of animal welfare. These changes, along with the company's new vegetarian offering, the BK Veggie sandwich, drew praise from the group.

In 2006, PETA went before Burger King's board of directors during its parent company's annual corporate meeting to request that poultry suppliers switched to a more-humane method of slaughter called controlled atmosphere killing (CAK). Instead of using its previous tactic of stating that the procedure is more humane, the group claimed that CAK was economically more feasible as it reduces the chances of injury to workers in poultry factories and it produces better products by preventing injury to the animal. Responding to the proposal in March 2007, Burger King announced it would make further changes to its animal-welfare policies. The new policies favor suppliers of chickens that utilize CAK rather than electric shock to knock birds unconscious before slaughter, and require its pork and poultry suppliers to upgrade the living conditions of pigs and chickens. Under the agreement, 2% of BK's North American egg suppliers are to use cage-free-produced eggs and 10% of pork suppliers are to use crate-free pigs for its pork products. PETA and the Humane Society of the United States were quoted as saying that Burger King's initiatives put it ahead of its competitors in terms of animal rights and welfare and that they were hopeful that the new initiatives would trigger reform throughout the fast food industry as a whole.

Nutrition

Since the 1980s, several parties, including the Center for Science in the Public Interest (CSPI), the City of New York, and the Spanish government, have argued that Burger King has contributed to obesity and unhealthy eating behaviors in Western nations by producing products that contain large amounts of salt, fat, trans-fat and calories. After its purchase by TPG Capital from former parent company Diageo in 2002, the company introduced several large, oversized products including its European BK XXL line, the Enormous Omelet Sandwich line and the BK Stacker line. These new offerings, and others like them, have resulted in further international scorn and negative attention due to the large portion size and increased amounts of unhealthy fats and trans-fats in these items. Many consumer groups have accused Burger King and other fast food restaurant chains of failing to provide healthier alternatives.

A 1985 agreement with the New York city public health commissioner's office, over publication of nutritional data regarding the food it sells, helped define guidelines used by the city for the dissemination of nutritional information. In a five-month negotiation with Burger King and its then parent Grand Metropolitan PLC (now part of Diageo), the company agreed to post complete nutritional information that complied with the Federal Government's guidelines for the maximum daily recommended intake of fat and sodium. Additionally the data was to be presented in a format easy for the general public to understand and use. On the basis of this agreement, New York public health commissioner Mark Green, with support of Mayor David Dinkins, proposed legislation that would require all fast food restaurants to display nutritional data as well.

In response to the 2006 introduction of the BK XXL product line in Spain, the Spanish Health Ministry publicly claimed that the company had violated a voluntary agreement between the company and the Spanish Federation of Hoteliers and Restaurateurs, a group to which Burger King belongs, that called on its members to refrain from advertising large portions of food. The Minister of Health, Elena Salgado, claimed that the new promotion and the new sandwiches, averaging over 970 calories each, violated the accord. The head of Spain's food regulatory body, Felix Lobo, stated a legal case could be made against Burger King for "illegally failing to comply with a contract". In a response to the Government's allegations, the European offices of Burger King released this statement: "In this campaign, we are simply promoting a line of burgers that has formed part of our menu in recent years. Our philosophy can be summed up with the motto 'As you like it,' in which our customers' taste trumps all." The company also explained that it had always worked "to reduce the risk of illness provoked by an inadequate diet and to promote a balanced ... diet." A spokesperson for the company stated that customers have the choice of salads versus a Whopper, that they have the option to modify their sandwiches as they please, and that the company was going to continue to advertising the products.

In May 2007, the Center for Science in the Public Interest (CSPI) sought a state-level class action lawsuit against Burger King in the Superior Court for the District of Columbia over the inclusion of trans-fats in foods served by Burger King and Burger King's failure to set a definitive time line for their elimination from the company's menu. The CSPI suit sought to require the company to place large health warnings on Burger King's food packaging that explained the dangers of trans-fat and the levels of trans-fat contained in its products. Burger King sought to move the case to the Federal courts and have the suit dismissed. The Federal Court denied the company's motion for dismissal and sent the case back to the Superior Court for trial. To address the CSPI's legal challenge, as well as several laws passed in New York City, Philadelphia and other cities regarding the issue of trans-fats in its food, BK announced a plan in July 2007 to phase out all trans-fats from its products by the end of 2008.

In response to the issue of childhood obesity, Burger King announced in October 2007 that it was joining The Council of Better Business Bureau's Children's Food and Beverage Advertising Initiative. The program is a voluntary self-regulation program designed to modify advertising messages aimed at children so as to encourage healthier eating habits and lifestyles. As part of its participation in the program, Burger King announced a series of steps in its advertising and children's product lines to which it was committing itself:

Restricting advertising to children under 12 that uses third-party licensed characters to Kids Meals that meet its Nutrition Guidelines Refraining from advertising in elementary schools and from product placement in media primarily aimed at children under 12 Promoting Kids Meals that meet its Nutrition Guidelines on its Web site Promoting healthy lifestyles and healthy dietary choices in advertising

The modified Kid's Meal line will include new products, such as broiled Chicken Tenders, apple "fries" (French cut, raw apples served in a fry box), and Kraft macaroni and cheese. According to the statement by the company's corporate parent, Burger King Brands, the meals will contain no more than 560 calories per meal, with less than 30 percent of the calories derived from fat, less than 10 percent of the calories from saturated fat, no added trans fats and no more than 10 percent of calories derived from added sugars. As of August 1, 2008, Burger King has introduced the product line in the United States, but not the broiled Chicken Tenders product available in the United Kingdom and Ireland.
