Human Factors
WE were flying the LOC approach to 24L. As we started down to our MDA we broke out and I started looking for the airport. I was making the call outs to MDA and thought the First Officer was stopping the descent at the MDA. I looked out and back and realized he was still descending and told him to stop descent. We stopped 150 feet below MDA; continued the approach and landed. Looking back at the approach I should have called for a missed approach and received vectors for another approach. The only reason for continuing was use of poor judgment or just a bad decision at the time.
A CRJ Captain reported the flying First Officer descended 150 feet below MDA on a LOC approach.
