On a sidewalk near Philadelphia's federal courthouse - where some of the same members of the coalition filed the federal suit in 1980 - Coard said the group would give the Corbett administration 10 days to meet its demands.
The original suit led to a 1999 settlement in which the state funneled $36.5 million to Cheyney for building and academic upgrades. Coard was student government vice president at Cheyney when the suit was filed.
The coalition declined to say how much it was seeking, though Coard said $250 million would be "a nice, round number."
Located on 275 acres of rolling farmland in Delaware and Chester Counties, Cheyney - founded in 1837 and one of the oldest historically black colleges in the country - has struggled for years with low enrollment and funding woes, as have many historically black universities. It faces a $14 million deficit and enrolls 1,200 students, down from nearly 3,000 in 1977, the coalition said.
Cheyney is known for giving underprivileged inner-city students a chance at a college education that other schools may not. More than half of Cheyney's students hail from Philadelphia.
The other 13 state universities, the group asserted, are running a $100 million surplus while Cheyney operates in the red.
"Racism," Coard said. "That's why we're pushing this issue."
In a statement, Peter Garland, acting chancellor of the state system, denied discrimination and said the system has allotted Cheyney the highest per-student funding of any of its universities. The system also has awarded Cheyney $70 million in capital funding over the last two years for a new residence hall and science center.
"Clearly, Cheyney University is treated fairly and equally in comparison to its other sister schools," Garland said, noting that the percentage of Cheyney's budget covered by tuition and fees is smaller than at the other schools.
Corbett's office, the state Education Department, and Cheyney president Michelle R. Howard-Vital did not respond to requests for comment.
The group was joined by U.S. Rep. Chaka Fattah, State Rep. Ronald Waters, and Philadelphia City Councilwoman Jannie L. Blackwell, also a Cheyney alumna, among others.
"We're here for the long haul," Blackwell said.
Also leading the news conference was Jeffrey K. Hart, an event planner and Cheyney alumnus who was part of the 1980 suit as student government president.
Alumni, he said, have become increasingly concerned, spurring him to review the lawsuit.
"I brought about 12 people together and decided this would be the action we'd take," he said.
Malik Williams, 21, student government president, said Cheyney buildings need work and better equipment.
"If we had more funding, we could build more things. We could grow," said Williams, a business administration major from Pittsburgh.
The coalition said the state system should revise its funding formula and exempt Cheyney from any "austerity measures" enacted at the other universities as budgets tighten.
