Rose Mary Knick makes no bones about it. She doesn't buy that there are bodies buried on her eastern Pennsylvania farmland, and she doesn't want people strolling onto her property to visit what her town says is a small cemetery.

Six years ago, however, Knick's town passed an ordinance that requires anyone with a cemetery on their land to open it to the public during the day. The town ordered Knick to comply, threatening a daily fine of $300 to $600 if she didn't. Knick's response has been to fight all the way to the U.S. Supreme Court, which heard arguments in her case Wednesday.

"Would you want somebody roaming around in your backyard?" Knick asked during a recent interview on her Lackawanna County property, which is posted with signs warning against trespassing.

Her neighbors in Scott Township, the Vail family, say they just want to visit their ancestors' graves.

The Supreme Court isn't going to weigh in on whether there's a cemetery on Knick's land. Instead, it's considering whether people with property rights cases like Knick's can bring their cases to federal court or must go to state court, an issue groups nationwide are interested in.

Knick, 69, says her town's ordinance wouldn't protect her if people injure themselves on her land and sue. And she says if the town is going to take her private property and open it up to the public, they should pay her. She says she believes that the town was trying to make an example out of her for questioning lawmakers' decisions.
