Alan Black, a Slidell lawyer who is running for 22nd Judicial District Attorney, has touted his judicial experience on the campaign trail, pointing out that he was appointed by the state Supreme Court to fill in as a judge in city courts in Slidell, Bogalusa and Hammond and that he has served as an administrative hearing officer for St. Tammany Parish.

But Black did not list the parish job, which pays $4,000 a month, on the personal financial disclosure statement that he filed with the Louisiana Board Of Ethics after he qualified to run for district attorney of St. Tammany and Washington parishes. Three other candidates are seeking that office: Roy Burns, Warren Montgomery and Brian Trainor.

Black said via email Wednesday that the job was left off in error.

“I resigned as the hearing officer for code violations with the St. Tammany Parish Bureau of Administrative Adjudication before submitting my personal finance disclosure,’’ he wrote. “In filing the disclosure, I no longer made income as the hearing officer, thus it was inadvertently omitted.’’

Black wrote a letter to Parish President Pat Brister on Aug. 6 saying that he was resigning the post because of his candidacy and asking that it be made effective Aug. 21. He filed his disclosure form Aug. 22.

However, the disclosure requirement pertains to the previous calendar year, in this case 2013, when Black was still serving as the administrative hearing officer. Black said Wednesday that he is proud of that work experience, which he has noted in forums and in campaign materials as unique to him.

“It should have been included; therefore, I have amended the report and will file it tomorrow,’’ Black said.
