Freddie Mac’s government conservator is stepping up to shut down a potentially costly lawsuit filed against the GSE by the Mortgage Guaranty Insurance Corp. both by legal and by extra-legal means. Last month, the Federal Housing Finance Agency told a Wisconsin federal court that it lacks jurisdiction over the pool insurance suit the mortgage insurer filed against Freddie. Given that the suit would impede FHFA in its capacity as the GSE’s conservator, the court should dismiss MGIC’s suit, according to court papers filed by the Finance Agency on July 20.
