1. For many years, the Supreme Court believed that "commercial speech" was entitled to less protection than other forms of speech. One defining element of commercial speech is that its dominant theme is to propose a commercial transaction. This kind of speech is protected by the First Amendment, but the government is permitted to regulate it more closely than other forms of speech. However, the government must make reasonable distinctions, must narrowly tailor the rules restricting commercial speech, and must show that government has a legitimate goal that the law furthers.

Edward Salib owned a Winchell's Donut House in Mesa, Arizona. To attract customers, he displayed large signs in store windows. The city ordered him to remove the signs because they violated the city's sign code, which prohibited covering more than 30 percent of a store's windows with signs. Salib sued, claiming that the sign code violated his First Amendment rights. What was the result, and why? 2. Jennifer is a freshman at her local public high school. Her sister, Jackie, attends a nearby private high school. Neither school allows them to join its respective wrestling team; only boys can wrestle at either school. Do either of them have a winning case based on the equal protection clause of the Fourteenth Amendment? 3. The employees of the US Treasury Department that work the border crossing between the United States and Mexico learned that they will be subject to routine drug testing. The customs bureau, which is a division of the treasury department, announces this policy along with its reasoning: since customs agents must routinely search for drugs coming into the United States, it makes sense that border guards must themselves be completely drug-free. Many border guards do not use drugs, have no intention of using drugs, and object to the invasion of their privacy. What is the constitutional basis for their objection? 4. Happy Time Chevrolet employs Jim Bydalek as a salesman. Bydalek takes part in a Gay Pride March in Los Angeles, is interviewed by a local news camera crew, and reports that he is gay and proud of it. His employer is not, and he is fired. Does he have any constitutional causes of action against his employer? 5. You begin work at the Happy-Go-Lucky Corporation on Halloween. On your second day at work, you wear a political button on your coat, supporting your choice for US senator in the upcoming election. Your boss, who is of a different political persuasion, looks at the button and says, "Take that stupid button off or you're fired." Has your boss violated your constitutional rights? 6. David Lucas paid $975,000 for two residential parcels on the Isle of Palms near Charleston, South Carolina. His intention was to build houses on them. Two years later, the South Carolina legislature passed a statute that prohibited building beachfront properties. The purpose was to leave the dunes system in place to mitigate the effects of hurricanes and strong storms. The South Carolina Coastal Commission created the rules and regulations with substantial input from the community and from experts and with protection of the dune system primarily in mind. People had been building on the shoreline for years, with harmful results to localities and the state treasury. When Lucas applied for permits to build two houses near the shoreline, his permits were rejected. He sued, arguing that the South Carolina legislation had effectively "taken" his property. At trial, South Carolina conceded that because of the legislation, Lucas's property was effectively worth zero. Has there been a taking under the Fifth Amendment (as incorporated through the Fourteenth Amendment), and if so, what should the state owe to Lucas? Suppose that Lucas could have made an additional $1 million by building a house on each of his parcels. Is he entitled to recover his original purchase price or his potential profits?
