Even if they say that in most cases a judicial hearing is not required, why even put it in that category?
Because in many cases judicial action is required. In a congregation in my city, a child abuser attempted suicide once he got to know that he has been outed. His attempt to suicide was a hoax to claim mental depression and wiggle out of a JC and the law. While elders were dealing with him compassionately, the police officers arrested him and gave him a beating of his life. He is behind bars.
The judicial hearing will not be for the attempted suicide, but for the reason behind it. and the reason behind attempting suicide or a pretense of attempting suicide is not always depression.
