Students said he was "rude, condescending, humiliating, and belittling," once screaming "shut up" at a student trying to answer a question from him, Benson wrote.
Attorney Robert Sykes said Maranville was doing "exactly what he was hired to do" and also had good reviews.
"It's a tough economy. He was demanding that they perform and perform well," Sykes said. "He wasn't going to sit up there and lecture them."
But the "volume and magnitude" of the negative student responses made UVU leaders see it differently, according to university attorney David Jones. Those students were "seasoned young adult students in an upper-level business course, with other real-life jobs and experiences," Jones, an assistant Utah attorney general, wrote in an email.
UVU cut Maranville loose, though it did give him another one-year contract so he had time to find new work.
After the year, he sued, saying his contract gave him a "reasonable expectation" of tenure or at least the right to have supervisors hear his side of the story, Sykes said.
"Our basic claim is, he had a right to notice and a hearing," he said. "He could still be terminated, but he had a right to notice and a hearing."
But Jones said Maranville was informed about the university's decision and didn't take the chance to appeal
Benson dismissed the suit in August, ruling that since the contract said tenure hinged on "successful completion" of a probationary period, along with acquiring written recommendations, Maranville didn't have the right to expect automatic tenure or a hearing.
Maranville, who subsequently taught at Westminster College in Salt Lake City and went into private business in August, is appealing to the 10th U.S. Circuit Court of Appeals in Denver.
He's seeking damages equal to the difference between the income he would have made at UVU and what he actually made at Westminster, Sykes said, he was paid $20,000 a year less than he was promised at UVU,
