Revolution: A Survey of Cases Involving
Paternity Testing
Timothy Caulfield*
The past few decades have witnessed the emergence of an increasingly inclusive
definition offamily in Canadian law. This trend is largely attributable to twofactors:
the dominance of the family law principle of the best interest of the child and an
understanding that relationships are more important than biological relatedness in
determining parental rights and duties. In light of the increasing pervasiveness of
genetic information in Canadian society, the author explores the degree to which a re-
emphasis on biological ties will alter how we define the concept offamily, both legally
and socially. To this end, he examines whether recent advances in human genetics,
particularly DNA paternity testing, have resulted in courts more frequently applying
the best interest test through the lens of biology and in a corresponding decrease in
courts' support of non-biological families.
The author examines Canadian case law involving paternity testing from 1992 to
1998 and finds no significant increase in either the number of cases brought to court or
the percentage of cases in which genetic testing was ordered. However, the author's
analysis suggests that courts are placing a growing value on the importance of genetic
evidence, and that they justify its use by reference to the importance of complete
medical information for thefuture health of the child, to the state's interest in ensuring
that a child receives financial support, and to the certainty which genetic evidence
affords.
The author argues that as genetic technology is in its infancy and the causes of medical
conditions are complex, the information provided by DNA testing is suspect. More
broadly, the courts should be wary of yielding to biological determinism, lest they
neglect other vitalfactors in considering what familial configuration is bestfor a child.
