"This thoroughly researched and informative book expertly charts the progress of this revolution across an impressive array of jurisdictions, national, international, and supranational, with a particular emphasis on the role played by the judiciary in advancing the legal recognition of same-sex couples. The text contains twenty-three expertly written chapters, each illuminating in its own right, but collectively providing a comprehensive and enlightening overview of the state of legal developments in this area." (Fergus Ryan, International Journal of Constitutional Law, Vol. 14 (1), January, 2016)
