A statement provided by a Vianney spokesman Monday said the school was disappointed by the judge’s decision. “We are consulting with our attorneys and evaluating our next steps,” the statement said.

The school sued Kirkwood in 2016; the case moved to federal court in St. Louis in 2017.

Kirkwood’s codes say the sound system may only be used between 7 a.m. and 10 p.m., and not more than 30 minutes before a scheduled athletic event. Its use must be limited to playing the national anthem and pregame announcements, and not for music, play-by-play or practices.

Vianney’s president has said city codes limit Vianney’s lights to about 40 percent of their capacity, creating an unsafe environment for competitive sports. The city, in court filings, says its lighting restrictions are designed “to strike a balance of safety and aesthetics” and “protect the public health, safety and welfare” of residents and homeowners from “intrusive light trespass from sports fields.”

Vianney, its contractor, Kirkwood officials and residents who live near the high school’s 37-acre campus fought for months over construction of the school’s new $1.5 million turf field, paid for by alumni donors and finished before the 2016 baseball season. The school paid $235,000 for its new lighting system.
