It is demonstrated that recent NMR results in 3He indicate that at 2.65 mK, the liquid makes a second-order transition to a phase in which the "spin-orbit" symmetry is spontaneously broken. The hypothesis that this phase is a BCS-type phase in which pairs form with l odd, S=1, Sz=\ifmmode±\else\textpm\fi1 leads to reasonable agreement with both NMR and thermodynamic data, but involves some difficulties as to stability.
