price that can be charged for given goods. Some states that do not have a specific statute addressing price gouging, can nevertheless apply the law as an "unfair" or "deceptive practice" under a consumer protection act. When the law goes into effect Statutory prohibitions on price gouging become effective once a state of emergency has been declared. States have legislated different requirements for who must declare a state of emergency for the law to go into effect. Some state statutes that prohibit price gouging—including those of Alabama, Florida, Mississippi, and Ohio—prohibit price increases only once the President of the United States or the state's governor has declared a state of emergency in the impacted region. California permits emergency proclamations by officials, boards, and other governing bodies of cities and counties to trigger the state's price gouging law. What the law prohibits State laws vary on what price increases are permitted during a declared disaster. California has set a 10 percent ceiling on price increases. Florida prohibits a price increase “that grossly exceeds the average price” of that same item in the 30 days leading up to the emergency declaration. Some state laws do not define what constitutes a “gross disparity,” making it difficult for either affected residents or law enforcement to determine when price gouging has occurred, while others merely limit vendors and landlords to price increases of less than 25 percent. Laws often include exceptions for price increases that can be justified in terms of the increased cost of supply, transportation, demand, or storage. Enforcement Enforcement of anti-price gouging statutes can be difficult because of the exceptions often contained within the statutes and the lack of oversight mechanisms. Statutes generally give wide discretion not to prosecute. In 2004, Florida determined that one-third of complaints were unfounded, and a large fraction of the remainder was handled by consent decrees, rather than prosecution. California California Penal Code 396 prohibits price gouging, generally defined as anything greater than a 10 percent increase in price, once a state of emergency has been declared. Unlike other states that require the President of the United States or the state's governor to declare a state of emergency, California permits emergency proclamations by officials, boards, and other governing bodies of cities and counties to trigger C.P.C. § 396. The prohibition lasts for up to 30 days at a time and may be renewed as necessary. Since October
