A critical analysis of available experimental and theoretical data on transition probabilities for spectral lines of singly ionized nitrogen was performed. J-file sum rule tests for the 3s-3p triplet supermultiplet in NII were performed on the basis of recently calculated and measured line strengths. It is shown that the inclusion of intersystem transitions in the analysis leads to a better agreement of the data with the J-file sum rule prediction.
