What does the court accept evidence that someone is a witch in The Crucible by Arthur Miller?

In Arthur Miller's play "The Crucible," the court does not accept evidence that someone is a witch based on concrete proof or rational reasoning. Instead, the court relies on hearsay, rumors, and spectral evidence (claims of seeing spirits or ghosts) to determine guilt. This lack of substantial evidence highlights the atmosphere of mass hysteria and paranoia that permeates the town of Salem during the Salem witch trials.
