Why did Sir Edward Coke object to King James I consulting judges separately?

Sir Edward Coke objected to King James I consulting judges individually and separately because it was a tactic used by the King—often with the assistance of Francis Bacon—to circumvent the collective judicial opinion of the bench. When the judges were consulted together, they tended to echo Coke’s defense of the supremacy of the common law against royal prerogative. By isolating the judges, the King sought to pressure them into supporting his interests rather than maintaining a unified, independent judicial stance.1
