A trustee for a Jacksonville pension fund has agreed to acknowledge accidentally violating a state ethics law — but his accuser says that’s not enough.

Peter Sleiman, who sits on the Police and Fire Pension Fund’s governing board, agreed this month to pay the Florida Commission on Ethics a $2,500 fine if the commission closes out its review of a 2010 complaint involving financial disclosure forms he filed with the state.

The commission will review the complaint Friday and decide whether to accept a settlement signed by a commission employee and Sleiman, a developer and lawyer whose pension post of more than 20 years is unpaid.

If it doesn’t accept the settlement, the commission will hold a probable-cause hearing that day and decide whether to move forward or drop the complaint.

The agreement said Sleiman’s disclosures for 2005 through 2009 were incomplete because they didn’t have a detailed-enough listing of properties he owns and because he had not checked off a box showing which of two ways his finances were counted.

Sleiman said a secretary prepared the forms based on what was filed the year before, and so the same problems were repeated year after year.

But the man who filed the complaint, Jacksonville resident Curtis Lee, argues Sleiman will be getting off easy if the commission approves the settlement. He said Sleiman left important information out of the disclosure and was too experienced for people to accept that as accidental.

“Given Mr. Sleiman’s intelligence, obvious wealth … and long tenure as an attorney and … [fund] trustee, his violations of the law must be presumed to have been knowing and willful,” Lee argued in a letter to the commission this week.

He argued that Sleiman wrongly left out information about debts he had, but Sleiman said a state examiner looked at that and concluded he had listed the liabilities the law required.

Lee is a critic of the pension fund, and Sleiman said the ethics complaint was an extension of that. “He’s basically terrorized the pension fund.”
