The hypothesis that the spin angular momentum of each galaxy in a binary results primarily from tidal interaction with its companion during galaxy formation is shown to imply a non-random distribution of the angle between the major axes of the images of disc galaxies in pairs. The observed distribution of this angle is inconsistent with the tidal hypothesis, and is consistent with a complete lack of correlation between the spins. When a stronger criterion for isolation is adopted, the results are still inconsistent with the tidal hypothesis, with reduced significance level.
