New Jersey Governor Phil Murphy’s administration fired 30 employees of a state authority that finances local school construction after an independent review found that his former appointee stacked it with friends, family and political contacts who were unqualified for their jobs.

All but three of those dismissed Tuesday from the Schools Development Authority had been hired by Lizette Delgado-Polanco, the former chief executive officer who resigned in April amid media scrutiny of her oversight. A review by an outside law firm faulted the agency for “patronage-type hires” that undermined its work.
