In The Crucible, the theme of justice is central, exploring the flawed nature of the legal system during the Salem witch trials. Arthur Miller critiques the corruption and hypocrisy within the courts, highlighting how hysteria and personal vendettas can distort justice. The play questions whether justice is truly served in a court of law, as the proceedings become a mockery of fairness and truth.

The court in Salem is depicted as a place where justice is not served. The judges, including Hathorne and Danforth, are predisposed to believe the accusers, primarily young girls. The quality of evidence is dubious, with a doll used as proof of witchcraft. Abigail Williams manipulates the court, turning the proceedings into chaos. The judges' inability to see through the lies and their reliance on questionable evidence demonstrate the failure of the legal system to deliver true justice.

Reverend Hale's role in the court proceedings further illustrates the theme of justice. Initially, Hale supports the court's actions, but he becomes increasingly troubled by the lack of concrete evidence. He states, "I am a minister of the Lord, and I dare not take a life without there be a proof so immaculate no slightest qualm of conscience may doubt it." Hale's growing conscience and his plea for legal representation for the accused highlight the court's shortcomings in delivering justice.

Giles Corey represents the common man's struggle against the court's injustice. His refusal to name his informant, even under the threat of death, underscores his integrity and the court's failure to protect the innocent. Corey's defiance and ultimate martyrdom expose the court's inability to distinguish between truth and lies, further emphasizing the miscarriage of justice.

Ultimately, the court's actions reveal a concern for maintaining authority over seeking truth. Danforth's refusal to postpone hangings, despite Reverend Hale's plea, shows a prioritization of appearances over justice. Danforth's insistence that the court's decisions reflect "God's law" illustrates the dangerous conflation of civil law with religious righteousness, leading to tragic consequences.
