According to a report on the internet portal ucanews.com on Tuesday, this is the first such investigative commission in the Catholic Church in Poland.
In justifying his move, Wazny explained that he was "concerned with the truth".
Without truth, love and the mission of the Church would not be possible. The aim must be to attain the truth, "even if it is very painful, because we are confronted with the fact that certain things must be clarified, cleared up, atoned for, repented of and started anew".
According to the report, Wazny appointed a retired prosecutor from Katowice to chair the commission of enquiry, which is also a first for the Church in Poland.
The committee should also include experts in secular and ecclesiastical law, history and archival sciences, psychology and psychotherapy as well as communication. In addition, an external audit will be conducted to clarify "pastoral, financial, legal, administrative and personnel" issues, the diocese said in a statement.
According to the statement, the commission is scheduled to begin its work in September. With regard to the working methods of the committee, the bishop explained that it should be modelled on the "best practices" of US dioceses in the investigation and examination of abuse cases.
Bishop: Commission should do pioneering work for the whole Church in Poland
Wazny expressed the hope that the investigative commission would carry out pioneering work for the entire Church in Poland and that other bishops would follow his example.
Last year, the Polish Bishops' Conference announced its intention to appoint an independent team of experts to investigate the matter.
However, it is still unclear when this will happen. Last year, the state commission for the investigation of abuse cases complained about the bishops' refusal to hand over files.
In 2021, the Vatican imposed disciplinary sanctions on more Polish bishops for dereliction of duty in connection with allegations of abuse than in any other country. Almost a dozen bishops, most of them emeritus, had to pay sums to a church foundation that supports preventive measures against sexualised violence against minors.
In addition, most of the penalised bishops are no longer allowed to take part in public services, either in their former dioceses or at all.
The diocese of Sosnowiec, where Wazny has now assumed the office of bishop, has repeatedly hit the headlines in recent years.
According to media reports, several trainee priests accused the rector of the local seminary of sexually abusing them in 2010.
The seminary was later closed.
Another incident followed last year: at an alleged sex party organised by a homosexual priest, a call boy is said to have fainted after taking sexual enhancers .
According to the media, the priest refused to allow the paramedics to enter his home, whereupon they called the police.
Critics spoke of a moral decline in the diocese, which they also blamed on the then Bishop Grzegorz Kaszak.
