Can a lay person or a group of lay faithful petition the Pope (Vatican) to de-canonize a Saint in light of new findings?

To be specific, I am talking about numerous views recently circulated in different articles saying the Sainthood of Pope St. John Paul II is questionable in light of the findings stated in the McCarrick Vatican Report: [Report on the Holy See’s Institutional on the Decision-Making Relating to Former Cardinal Theodore Edgar McCarrick (1930 - 2017)](http://www.vatican.va/resources/resources_rapporto-card-mccarrick_20201110_en.pdf) . There are views that St. John Paul II had committed an "error in judgment", was deceived by McCarrick and had committed imprudent action in judging the case. Upon reviewing and analyzing the McCarrick Report, I saw that John Paul II had acted with prudence and prayerfully discerned and had judged correctly the allegations and anonymous accusations on Cardinal Theodore McCarrick when he was still a Bishop in the 80's. 1. Pope John Paul II had read the letter of Cardinal O'Connor summarizing the allegations and anonymous accusations. 2. Pope John Paul II even though the summarized letter had not presented a credible evidence, wisely instructed the US Nuncio and the Nuncio instructed four US Bishops to make an honest report on all the knowledge they know about the allegations on Cardinal McCarrick. 3. Pope John Paul II waited for the US Nuncio report to confirm if the allegations have foundation. 4. Pope John Paul II reflected on his own experienced in Poland where Priest and Bishops were victims of false accusations from communist group to destroy their reputation and weaken the Church. 5. Pope John Paul II in spirit of fairness also considered the letter of Cardinal McCarrick in defending his dignity. 6. Pope John Paul II after the failed assassination attempt boldly proclaimed his life was saved by Our Lady, and his new life from now on is totally consecrated to Our Lady, Totus Tuus. It follows that John Paul II discernment and judgment had seek the guidance of Our Lady to know the Truth behind McCarrick allegations. Will Our Lady allow Pope St. JOhn Paul II to be deceived? I don't think so. 7. Pope John Paul II as "anointed" Vicar of Christ enjoys the charisma of the Holy Spirit to guide him in all his judgment that may affect or even more scandalize the Church. Reviewing and analyzing carefully the McCarrick Vatican Report had shown that Pope John Paul II had prayerfully discerned and acted with prudence in judging the case, and John Paul II judgment had found that the allegations had no foundation and McCarrick was just a victim of character assassination. However, the McCarrick Vatican Report also stated that the four US Bishops had made an incomplete report and may have lied to John Paul II and concluded that it might have caused the wrong judgment on the part of Pope John Paul II. In light of this development, can the Church who had beatified and canonized not just a Saint but a Great Saint accept a petition to review his sainthood? The Tradition of the Church stated that the Church united to Peter is guided by the Holy Spirit it cannot err, how can it accept the circulating views coming from laity, clergy and prelates that Pope St. John Paul II might have committed an "error in judgment" and his path to Sainthood was done hastily. Thus my question: > **Can a lay person or a group of lay faithful petition the present pope (Vatican) to de-canonize a Saint in light of new findings?**
