"As to Mazuz's opinion (Attorney General Menachem Mazuz's decision to absolve the prime minister in the public sphere), in this matter I am less satisfied. There was room to phrase it differently, and I tried to make my contribution to the matter."

This is what Shimon Dolan said in his first-ever interview. Dolan retired four months ago as the head of the economic department in the State Prosecutor's Office; no replacement has been named yet.

Dolan was one of the team of four attorneys who studied the evidence in the Greek island affair, recommending not to put the prime minister on trial. Mazuz adopted the team's recommendation. Nevertheless, there is clearly criticism in his words about Mazuz's addition to the four's recommendation - to cleanse Sharon not only legally, but also in the public sphere.

"As to the evidence - it was highly likely that Prime Minister Ariel Sharon would have been acquitted if he was indicted in the Greek island affair. I am separating between intent and evidence - and this is the professional tool I use for the legal test on the question of whether there is sufficient cause to indict and what are the chances of conviction - and to keep this separate from the feelings that I have from reading the investigative material. In terms of the evidence, I am comfortable with the decision."

Dolan founded the economic department and headed it for the past 10 years. This made Dolan the senior prosecutor in the economic field, and he was responsible for all the serious financial and economic cases over the past two decades - the insurance cartel, the Bank of North America, Gergory Lerner, the German pensions, La Nationale, Gad Zeevi, Michael Chernoy and many others.

Dolan spoke to Haaretz about the increasing sophistication of financial crimes in Israel and about the need to unite forces of all the investigative agencies dealing with economic and financial matters. "The Trade Bank affair would not have happened in that manner if the police, the anti-money laundering authority and the tax authorities had cooperated," said Dolan.

Dolan revealed in the interview that he felt the senior management of Bank Hapoalim, led then by Amiram Sivan, should have been investigated in light of case of the bank supplying credit for the purchase of mutual funds by customers in 1993, and not only branch managers, but the police prevented it.

According to Dolan, in the La Nationale insurance affair - where the firm collapsed in the 1990s after presenting fictitious profits - he recommended indicting the owner Yossi Hackmey, and directors Bar-Kochva Ben-Gera (until recently the CEO of the Phoenix insurance company) and Professor Haim Ben Shahar. In the end they were not put on trial.
