In 1996, the president of Moldova appointed Djeta Chistol as a judge in the Center District Court of Chisinau. Five years later President Vladimir Voronin confirms her status until her reach of retirement age.

In 2012, Mrs. Chistol became a target of laughter in the media for errors in a ruling - she wrote there that “a car moved along three streets simultaneously.” The judge then blamed the work load and the High Council of Magistrates (CSM) decided to ignore the errors, which were meanwhile removed and the ruling was issued in a rectified version.

Two years later CSM awards Mrs. Chistol the third degree justice status for “high professionalism, special merits in the judiciary sector, and exemplary fulfillment of duties.”

In 2016, Djeta Chistol is the one who considered the case Diaspora vs. Moldova, a collective suit filed by more than 100 Moldovan migrant workers against the Central Election Commission, the Foreign Ministry, and the Government over violation of their right to cast the votes. The reason is that during the second round of the Moldovan presidential election (13 November 2016), 14 voting sections had run out of ballot tickets before they were closed.

Presiding over the first instance court, Mrs. Chistol awarded victory to the official authorities, stating in the verdict that they had acted in compliance with the laws in effect in regards to the citizens who were unable to cast their ballots. This verdict was maintained by the Court of Appeals and the Supreme Court of Justice, rejecting all claims from diaspora lawyers.

Since January 2019 Djeta Chistol is part of a judge panel that has been reviewing the second criminal case against former prime minister Vladimir Filat, who is charged with money laundering.

One year later the magistrate received the case against the ex-director of the Anticorruption Prosecution Office, Viorel Morari, but she declined it over what she called a “possible conflict of interests.”
