As the school year ends, Marin Acevedo, 14, is already looking ahead to September, but the view is hazy.

In January, city officials announced that they were shutting the charter school Marin attends, Williamsburg Charter High School in Brooklyn, because of concerns about its management. Court proceedings have stalled the city's efforts, and the freshmen, sophomores and juniors who intended to stay on at the school still have no idea whether it will be open in the fall.

Regular classes ended last week, and the school’s teachers, students and parents are waiting for Judge Ellen M. Spodek to rule.

The wait has been agonizing, said Barbara Marin, Marin’s mother. (His first name is his mother’s last.) “I’d rather have an answer one way or another than to drag it out,” she said.

The legal battle over Williamsburg Charter has put its students in an unusual situation.

The city announced it would shut down four charter schools at the end of this school year. One of them, Believe Northside Charter High School, was later spared by the city. Its sister school, Believe Southside Charter High School, will close as planned.

But Williamsburg Charter and Peninsula Preparatory Academy Charter School sued to remain open and won temporary restraining orders in the spring. Last month, Peninsula Preparatory received an extension of the order, making it likely the school will remain open this fall, said Kevin Quinn, the school’s lawyer.

The fate of Williamsburg Charter remains up in the air.

Though the city has shut more than 130 schools in the last decade, almost all of them have been phased out over time, allowing the students enrolled in them to graduate without disruption. But charter schools are typically closed immediately, meaning students must find new schools.

Before this year, the city had closed only six charter schools, and none of them wound up in a legal battle like Williamsburg Charter's.

About 20 of Williamsburg Charter’s 870 students have made arrangements to attend other schools, said James Tulley, an assistant principal. But the others seem to be sticking it out.

“I think the bulk of kids are hoping we’re going to stay open,” Mr. Tulley said.

Their parents seem anxious though. The school has seven staff members who field phone calls and e-mails from parents, Mr. Tulley said, and each of them receives one or two requests for updates a day. “It’s frustrating for them, because we have nothing new to tell them,” he said.

Some, like Ms. Marin, have made backup plans. In April, she e-mailed the principal of the Manhattan Village Academy, a public school on West 22nd Street, and asked him to interview her son for a spot there. “I e-mailed this principal and kind of begged him,” she said. He acquiesced, and Marin may be able to transfer there if Williamsburg Charter shuts down.

But Marin, a curly-haired freshman who speaks in short bursts, would rather stay at Williamsburg Charter. “Marin’s always done well in school, always,” Ms. Marin, who works for the state, said in an interview with her son at their brightly painted apartment in Gowanus, Brooklyn. “But this is the first year that I see that he enjoys school.”

The Williamsburg situation is even more unusual in that the city is trying to close the school because of concerns about its management and finances — not for academic reasons.

Though the school earned a "C" on its last city progress report, it is well-regarded by many of its students and their parents. Scores of parents packed a courtroom during a hearing last month. Monica Serrano, whose son attends Williamsburg Charter, said she wanted her daughter to go there, too. And Ms. Marin said she valued the school’s long hours and the uniforms students must wear.

“I do good in the school,” Marin said, and paused for a moment to think. “I do well in it.”

Ellen K. Eagen, Williamsburg Charter’s lawyer, said on Monday that she expected a ruling from Judge Spodek any day now. But the fight over the school’s fate could continue if either side appeals the decision.

Asked if the city planned to appeal should the ruling be in favor of the school, Elizabeth Thomas, a spokeswoman for the city’s Law Department, declined to answer. “We strongly believe that the D.O.E. appropriately revoked the school's charter given the circumstances,” she wrote in an e-mail. “It would be premature to comment further without seeing the decision.”

As for the school, Ms. Eagen said, “At this time, I would say that, yes, we are going to be appealing.”
