The news report as stated is somewhat inaccurate. The court actually declare 7-0 that gay couples are entitled to the same rights and privileges as straight couples. The split comes in how the rights are to be extended. Four justices directed that the legislature decide whether marriage be expanded, or whether a "separate but equal" form of union be created. The three "concurring and dissenting" justices felt that marriage rights should be granted, period.
News sources don't always get the facts right.
