U.S. Middle District Attorney Thomas A. Marino said yesterday that decision will take time because there is "a lot of reading to do" to determine if the statements rise to the level of a crime.

"I want to question a couple of people who were present," he said. They will not include Judge John E. Jones III, who presided over the case, he said.

Marino's comments came a day after Jones struck down the school district's policy of telling ninth-grade biology students Darwin's theory of evolution is not fact and intelligent design is an alternative explanation of the origin of life.

In his opinion, Jones accused some of those who testified during the six-week trial in Harrisburg of lying, singling out former board members Alan Bonsell and William Buckingham, the leading proponents of the policy.

Both men testified during the trial, which ended last month, and both gave sworn statements in depositions on Jan. 3. During the trial, Jones and lawyers for parents opposed to the policy confronted the men about the discrepancies and evasiveness in their answers to questions about their motivations and efforts to raise money for a pro-intelligent design textbook, "Of Pandas and People."

During the trial, after questioning by Jones and lawyers, Bonsell and Buckingham acknowledged that Buckingham raised money for the books in his church, then wrote a check for $850 to Bonsell's father, who bought the texts and donated them to the school district. Neither man disclosed the transaction in their deposition.

"The inescapable truth is that both Bonsell and Buckingham lied at their Jan. 3, 2005, depositions about their knowledge of the source of the donation for Pandas. ... ," Jones said in his ruling. "This mendacity was a clear and deliberate attempt to hide the source of the donations by [Bonsell and Buckingham] to further ensure that Dover students received a creationist alternative to Darwin's theory of evolution."

"Pandas" is a pro-intelligent design book written by creationists.

Jones also questioned the "credibility" of statements by other school officials and former board members.

In an interview, Buckingham called Jones a liar and denied making false statements. Bonsell has said he "tried to be as truthful" as he could.
