Although there were several attempts in Congress, no law was ever passed. There are several reasons why we as yet have no law. When anti-cloning laws were initially proposed, it was difficult to write a law that would permit potentially beneficial experiments in cloning tissues and organs while prohibiting cloning of entire human beings. Researchers protested that proposed laws would hinder beneficial research. California recently passed a law against cloning.
Several nations have laws prohibiting cloning.
These include Australia, Austria, Denmark, France, Germany, Norway, Slovakia, South Africa, Spain, Sweden, Switzerland, and the United Kingdom. Canada's Bill C-47 is that country's failed attempt at government regulation of cloning. Bill C-47 would have prohibited human cloning along with a list of other procedures related to assisted reproduction. Bill C-47 never became a law. For instance, it could have been interpreted so as to prohibit the hamster-egg test for viability of human sperm, which is a standard procedure in infertility treatment.
