Officials cracked down on illegal parking by court employees in Chinatown yesterday after the Daily News exposed the practice - but the lesson apparently didn't reach the Bronx courthouse.Yesterday afternoon, The News spotted 15 double-parked cars on Sheridan Ave. between 161st and 163rd Sts. More than one-third of those vehicles had government-issued parking placards in the windows.Capt. Pat Kelly, who supervises court officers in the area where The News found double parking, said, "We don't let people double-park. I don't know what's going on."Some of the double-parked cars were moved within minutes after The News approached Kelly.Kay Sarlin, a spokeswoman for the city Department of Transportation, said, "Parking permits do not authorize double parking and anyone caught doing so will be ticketed."The News also spotted three judges' cars with court placards parked in a loading zone on nearby Carroll Place. A city official confirmed late in the day that judges have the right to park in loading zones for an unlimited number of hours."These are judges' spots cause it's in front of the building," one court officer said.City and court officials promised yesterday to crackdown on illegal parking by government workers citywide in response to an exclusive report in yesterday's News documenting how court officers in Chinatown helped their colleagues obtain illegal parking spots on the sidewalk along Mulberry St."If there's improprieties taking place we'll address them as quickly as we addressed the one downtown," vowed David Bookstaver, a spokesman for the state Office of Court Administration. "We take it seriously."Stu Loeser, a spokesman for Mayor Bloomberg, said the mayor's Community Assistance Unit is working with the NYPD "to fix these problems and stop them from coming back."Matthew Roth, an official with Transportation Alternatives, an advocacy group documenting the widespread abuse of government parking placards, said the problem is citywide."It's bigger than a few court officers downtown, and the problem won't be solved with local short-term enforcement blitzes," Roth said. "Mayor Bloomberg needs to change the culture of privilege among government workers with a sustained crackdown on illegal parking citywide."Paul Browne, the NYPD's top spokesman, said the parking situation has "improved significantly" in the Chinatown area since The News began exposing this problem this year."But it requires continuous attention," Browne conceded.Yesterday, it was a new day on Mulberry St.When a woman in a Hyundai Sonata tried to park on the sidewalk one of two court officers stationed there told her, "They don't want anybody parking on the sidewalk."She complied.
