Some litigators likely had Hurricane Irma flashbacks Friday when the power went out for a few hours at the Miami-Dade County Courthouse.

The outage, which started before opening time at the 73 W. Flagler St. building, sent 12 judges trudging up the block to hold hearings at the Lawson E. Thomas Courthouse Center at 175 NW First Ave. Electricity was on again by about 11:15 a.m. at the 89-year-old civil courthouse, said Miami-Dade Circuit spokeswoman Eunice Sigler.

Other than employees, people arriving at the courthouse during the outage were turned away.

The power loss was caused by a breaker that tripped at a Florida Power & Light Co. substation, according to the county’s internal services department. The problem also knocked out the electricity at the nearby Miami-Dade Cultural Center, which houses the county’s main library and the HistoryMiami Museum.

FPL is done with post-hurricane power restoration for its 1.1 million Miami-Dade County customers, according to the utility company’s website.
