Step-by-step explanation:
When considering AG v. Williams, the question seems to be referencing a court case discussing legal principles, but it is not immediately clear which case is being referred to. Instead, the information provided appears to be about the case Gideon v. Wainwright, a landmark Supreme Court case. This case established the right to counsel in criminal cases, ensuring that defendants are provided with an attorney even if they cannot afford one, hence affecting the criminal court system. It overturned previous decisions and set a precedent that the burden of proof is on the prosecution, aligning with the benefits provided to the accused by the Bill of Rights. Another important principle mentioned pertains to the grand jury's role in prosecuting serious crimes and its exceptions. It rounds off with an explanation of the relationship between Gibbs Free Energy (ΔG) and work, a concept from chemistry rather than law, that was also included in the provided information.
