Wiwinius, who will retire on 2 July and is to be succeeded by Roger Linden, stressed that he is convinced that Luxembourg's residents "have confidence in the justice system".
Nevertheless, Wiwinius acknowledged that one of his major regrets is that the National Judicial Council was not introduced during his mandate.
This body's powers will include appointing and promoting the Grand Duchy's judges, which should guarantee the independence of the judiciary.
Its introduction is still planned for this legislative period. The new body also needs to be enshrined in the new constitution. The Council of State has already provided its official assessment.
Following the visit of EU Commissioner Didier Reynders, the issue of how many members will sit on the Judicial Council was brought up again, something which Wiwinius compared to "opening a can of worms".
When asked about the controversy regarding the judicial database JUCHA, in the context of which Wiwinius and Prosecutor General Martine Solovieff had written a letter to the President of the Chamber of Deputies, Luxembourg's Chief Justice stated that the case is now "closed".
Wiwinius also stated that he is happy with the latest version of the country's constitution, which once again describes the concept of judicial power in the section on the judiciary.
In order to reduce the time taken up by individual lawsuits, a civil law reform is planned. The authority of justices of the peace is to be expanded in order to cover legal disputes up to €20,000 and written procedures are to be replaced by oral ones, for instance, for appeals.
Written documents drawn up by lawyers are to be substantially reduced, both in length and number.
Criminal law is also to be slimmed down by having only a single judge preside.
The President of the Parliamentary Commission for Judicial Affairs, Charel Margue, has also confirmed to RTL that MPs will vote on the law regarding the efficiency of the judiciary in June.
Wiwinius rejected the accusation that the judiciary hesitates to prosecute financial crimes.
A major challenge at the moment, according to Wiwinius, is that there are not enough people who want to become judges in Luxembourg. Wiwinius wonders whether this might have something to do with the fact that lawyers are better paid than judges in Luxembourg. While he rules out the possibility of opening up the positions to non-Luxembourgish nationals, Wiwinius describes the plans to hire 45 trainees as a "ray of hope".
Finally, the Chief Justice stated that the government's Covid-19 restrictions, such as the curfew, have been "appropriate" and have not overly limited the population's personal liberties.
