 John Locke famously characterized the relationship between a person and her body as self-ownership. However, other philosophers have held that persons are stewards of their bodies rather than owners (Honore 1961). In medical contexts, under rubrics of privacy, individuals are sometimes ascribed rights of self-ownership and the ownership of parts and products of their bodies (Moore 2005). In this vein, a philosophically interesting invasion of privacy argument was advanced in the landmark California case Moore v. Regents of the University of California (1990). Without his knowledge or consent, University of Southern California research physicians developed a commercial cell line from tissue removed from leukemia patient John Moore. Moore and an appellate court argued that in taking his DNA-laden tissue for unrevealed research and development purposes unrelated to Moore’s cancer care, UCLA doctors had appropriated Moore’s identity in a manner analogous to advertisers using a person’s photograph without consent for commercial gain. Moore’s privacy claim was novel at the time, but the claims of celebrities and others to control the attributes of their personal identities—likenesses, voices, names, monikers, trademarks, and Social Security numbers—are commonly styled as privacy rights and have been since the early 20th century. John Moore’s privacy claim was not successful in court. The California court held that Moore’s doctors ought to have obtained his informed consent; but the court was unwilling to commodify human tissue or DNA as private property (Radin 1987). Nor did the court think Moore’s injury fit the mold of traditional invasions of privacy recognized in the law. In a related case that did not result in tort litigation in her lifetime, cells taken from Baltimore resident Henrietta Lacks were the basis of an important immortal cell line, HeLa. Lacks died in 1951, but the cell line created using her cervical cancer cells without her knowledge or consent lives on. It has been used in the treatment and eradication of numerous conditions and illnesses, including polio, without any financial reward to her or her heirs.
