He and four other theologians were nominated for honorary degrees by the Swiss Papal university at Fribourg. This needed Vatican approval. Weakland and two others were vetoed, so the university responded by rescinding all five nominations. Weakland was not officially censured by the Vatican. It respected his authority as Bishop to act according to his own conscience.
Priests are even less secure than bishops.
The Swiss Hans Kung was removed as professor of theology at a German university. He had written against the idea of papal infallibility, and had recommended that all dioceses enjoy the right to appoint their own bishops, citing a Swiss example which had received this privilege centuries ago. In 1986 Father Curran, professor of moral theology at the Catholic University in Washington, D.C. was removed. He had written controversial views about birth control and homosexuality. Canon law denies all of this.
