Legal professional privilege  In common law jurisdictions, legal professional privilege protects all communications between a professional legal adviser (a solicitor, barrister or attorney) and his or her clients from being disclosed without the permission of the client. The privilege is that of the client and not that of the lawyer. The purpose behind this legal principle is to protect an individual's ability to access the justice system by encouraging complete disclosure to legal advisers without the fear that any disclosure of those communications may prejudice the client in the future. The common law principle of legal professional privilege is of extremely long standing. The earliest recorded instance of the principle in English case-law dates from 1577 in the case of "Berd v Lovelace the full report of which states:  The principle originated as protection for individuals when accessing the knowledge and legal resources available to a lawyer and was said to stem from the "oath and honour" of the lawyer, a sort of special contractual relationship. It was based on the fact that the ordinary citizen could not safely navigate the complexities of the law and justice system without some assistance. However, without protection the quality of the advice would suffer as clients would be discouraged from making full disclosure to their legal representatives. As Lord Brougham put it in "Greenough v Gaskell" (1833):  "The foundation of this rule is not difficult to discover. It is not (as has sometimes been said) on account of any particular importance which the law attributes to the business of legal professors, or any particular disposition to afford them protection ... But it is out of regard to the interests of justice, which cannot be upholden, and to the administration of justice, which cannot go on without the aid of men skilled in jurisprudence, in the practice of the courts, and in those matters affecting rights and obligations which form the subject of all judicial proceedings. If the privilege did not exist at all, every one would be thrown upon his own legal resources, deprived of professional assistance, a man would not venture to consult any skilful person, or would only dare tell his counsellor half his case"." In England and Wales, the rules on legal professional privilege are set out in common law. The Civil Procedure Rules 1998 ('CPR') Rule 31.15 establishes a right to inspect documents in civil litigation, and provide that a party to whom a document has been disclosed (i.e. mentioned or relied upon in litigation) has a right to inspect that document (if such inspection would be proportionate given the nature of the case) - except where the party making disclosure has the right to withhold such inspection.
