It was the publication of this book that inspired Mr. Leadbitter M.P. to ask the Prime Minister to make the statement from which the quotation (infra, n. 3) is taken. Since then, the literature has proliferated.

⁸ According to the O.E.D., a grasser is “one who gives information”, and the word has its origins in rhyming slang: grasshopper—copper (or policeman). Public awareness of supergrasses has been heightened by the use in Northern Ireland of “converted terrorists” as informers and witnesses. See further below, p. 325, n. 18.

¹⁴ H.C.Deb., Vol. 12, col. 12 (9 November 1981). On the same day as the Attorney-General made his statement about immunity the Prime Minister disclosed in a written reply that a Mr. Leo Long, a former associate of Mr. Blunt who had also admitted espionage, had been refused immunity from prosecution “but was told that he was not likely to be prosecuted if he cooperated in the Security Service's inquiries,” H.C.Deb., Vol. 12, col. 40 (9 November 1981). The Attorney-General stated that he would not prosecute Mr. Long for treason.

¹⁵ Presumably, as a result of questioning following a promise of immunity.

¹⁹ For discussion of the disappearance of the practice, see A. T. H. Smith, “The Prerogative of Mercy, the Power of Pardon and Criminal Justice” [1983] P.L. 398. The most spectacular modern use of the power was the pardon granted by President Gerald Ford to former President Richard M. Nixon.

²⁰ See generally J. LL. J. Edwards, The Law Officers of the Crown, pp. 227–237. Courtesy to the court would no doubt lead the prosecutor to express the point less bluntly. But the legal position was stated by Viscount Dilhorne in Gouriet v. Union of Post Office Workers [1978] A.C. 435 as follows: The Attorney-General “merely has to sign a piece of paper saying that he does not wish the prosecution to continue. He need not give any reasons.” And see the anonymous article “Nolle Prosequi” [1958] Crim.L.R. 573.

²¹ This caused the government of the day some embarrassment when it emerged that it was unable to intervene to withdraw a prosecution against a visiting Russian athlete, Nina Ponomareva. See [1956] Crim.L.R. 725.

The extent to which the courts might seek to control the Director's decision to offer no evidence is considered infra, p. 311. Offering no evidence is a well established method of making an accomplice competent: Rowland (1826) Ry. & M. 401; 171 E.R. 1063; Owen (1839) 9 C. & P. 83; 173 E.R. 751; O'Donnell (1857) 7 Cox C.C. 337.

²⁴ See Mr. S. Silkin, H.C.Deb., col. 424 (21 November 1979). The decision was not ratified, apparently, by Sir Elwyn Jones during his period of office as Attorney-General: ibid.; but Mr. Silkin advised the Cabinet Office that his predecessor in office, who had by this stage become Lord Chancellor, should be informed. Although it is by no means clear precisely what offences Blunt had committed, the most obvious charges would seem to have been offences under s. 2 of the Official Secrets Acts 1911, in which case the consent of the Attorney-General would have been required before a prosecution could be brought. The immunity would therefore have implied a promise not to grant the statutory consent. But this would not, in principle at least, have been binding on a subsequent Attorney-General, since it would constitute an attempt to fetter either his own or his successor's discretion.

Miller, Presidential Power (1977), p. 312, where it is said that the power to pardon “permits the President to issue general amnesties by proclamation, by which entire classes or communities are pardoned;” U.S. v. Klein, 80 U.S. 128 (1872).

²⁶ Supra, nn. 4–5.

²⁷ Technically, the pardon must be countersigned by a Secretary of State, not necessarily the Home Secretary: Criminal Law Act 1967, s. 9; and there have been occasions when the Foreign Secretary has taken responsibility for using the prerogative to release convicted spies. The most recent study of the operation of the prerogative is C. H. Rolph's The Queen's Pardon (1979). The Home Secretary's accountability to Parliament for the exercise of the pardon is considered in G. Marshall, “Parliament and the Prerogative of Mercy” [1961] P.L. 8.

²⁸ A. F. Wilcox, The Decision to Prosecute (1972), p. 110. The amnesty also applied to persons who had already been convicted, including three M.P.'s, in which case it would more properly have been referred to as a pardon.

²⁹ Ibid. No similar amnesties have been given since then.

⁷⁰ According to a newspaper report, the matter arose before the High Court in Leeds over a baby-snatching case, when the Director of Public Prosecutions declined to prosecute a father for kidnapping and his parents for perjury. The judge twice ordered the Director to consider the matters and to tell the police what further evidence was required and then if he still advised against prosecution, he was to detail his reasons for that decision. “At the D.P.P.'s office, this order was thought to represent a possible risk to the Director's constitutional position, especially if it set a precedent by which he might have to give a detailed explanation of every decision he took. Therefore on behalf of the D.P.P. the Treasury Solicitor applied to the High Court to have the decision reworded”; E. Dunn, The Sunday Times, 31 October 1982.

⁷¹ (1978) 68 Cr.App.R. 281. In Beresford (1952) 36 Cr.App.R. 1, the trial judge refused to permit the prosecution leave to withdraw, and an adjournment was taken so that the Attorney-General could decide whether to enter a nolle prosequi, which he did.

⁷² R. v. Canterbury and St. Augustine Justices, ex p. Klisiak [1982] Q.B. 389. Where a summary prosecution is wholly withdrawn, the court clerk must report the matter to the Director of Public Prosecutions, which might act as a check on the actions of the police where there is a suspicion that a deal has been made: Prosecution of Offences Regulations 1978, r. 9.

⁷⁵ I am grateful to the office of the Director of Publications for supplying me with a copy of the transcript of their Lordships′ speeches and for arranging permission to cite from it. The Director of Public Prosecutions of the day, Sir Norman Skelhorn, has written about the incident in his autobiography Public Prosecutor (1982), p. 104, and states that he is unrepentant in his view that he was right to have granted immunity to Smalls. The New Zealand courts have also looked with equanimity upon a written grant of immunity conferred by the Solicitor-General in McDonald [1980] 2 N.Z.L.R. 103, where it was argued that the Solicitor-General had no power to grant an immunity before the indictment was preferred. The Privy Council ruled otherwise, although it did not decide whether or not the immunity bound the Crown as a matter of strict law (1983) 133 N.L.J. 514.

⁷⁹ Dyson v. Attorney-General [1911] 1 K.B. 410. What would happen should the use of the power become widespread is unclear. For that matter, how could the courts detect an increase in the use of the power? No statistics are kept, but the occasional parliamentary reply suggests that its formal usage is sparing; in 1976 it was used on four occasions, and in 1977. six. See H.C.Deb. Vol. 945, col. 15 (1978).

⁸⁰ See Viscount Dilhorne in Gouriet v. Union of Post Office Workers [1978] A.C. 435.

⁸¹ In Cherry (1871) 12 Cox C.C. 32, the court ruled admissible inculpating statements made in the course of an examination in bankruptcy, notwithstanding that a promise had been given not to use them. But as the court noted, the defendant was obliged to submit to examination under the Bankruptcy Act, and the position might have been different had the admission been voluntary. Cf. the American rule which gives the courts power to terminate a prosecution brought in breach of an agreement not to prosecute. People v. Bogolowski, 148 N.E. 260 (1925); 157 N.E. 181 (1927, S.C. of Illinois).

⁸² Gould (1840) 9 C. & P. 364; 173 E.R. 870; Baker [1941] 2 K.B. 382 discussed by Glanville Williams, “Evidence Obtained by Illegal Means” [1955] Crim.L.R. 339; A. Gotlieb, “Confirmation by Subsequent Facts”(1956) 72 L.Q.R. 209. In America, by contrast, it must be shown that the evidence is “derived from a legitimate source wholly independent of the compelled testimony.” See U.S. v. Kastigar, 406 U.S. 441 (1972).

Leroux [1981] Crim.L.R. 631, the Divisional Court declined to interfere with a conviction under the blood-alcohol provisions of the Road Traffic Acts when the appellant had destroyed a potentially self-exculpating sample after receiving a letter saying that he would not be prosecuted. Cf. Moevas v. Department of Labour [1980] 1 N.Z.L.R. 464, where the authorities (including Connelly v. D.P.P. [1964] A.C. 1254; Humphreys [1977] A.C. 1) are discussed, the view is taken that the courts have an inherent jurisdiction to stop a prosecution where they take the view that it is oppressive. Cf. however, Rourke [1977] 76 D.L.R.(3d) 193 where the Supreme Court of Canada took a contrary view.

⁸⁷ One part of the agreement signed by the Director of Public Prosecutions read “should Smalls refuse to give or refrain from giving evidence to the best of his ability … this statement shall have no effect.” Because of the pressure that this might place on the witness to varnish the truth so as to be seen to be keeping his part of the bargain, this seems objectionable in principle.

⁸⁸ Farler (1837) 8 C. & P. 106, 108.

⁸⁹ It was suggested in Archbold, Criminal Evidence, Pleading and Practice, 40th ed. (1982), para. 1425a, that “a general rule seems to be developing that when a witness in a criminal case, whether he be a fellow-accused or called for the Crown, may reasonably be regarded as having some purpose of his own to serve which may lead him to give false evidence against an accused, the judge should warn the jury of the danger of convicting that accused on that witness's evidence unless it is corroborated.” See, however. Beck (1981) 74 Cr.App.R. 221, where the court disapproves the passage, saying that there is no obligation to give the accomplice warning if there is no reason to suggest that the witness is a participant. In Stainton [1983) Crim.L.R. 171, the Court of Appeal held that the appropriate warning was a matter for the judge, where he had concluded that a witness might have an axe to grind.

⁹⁰ The case went before the Court of Appeal on five occasions, only one of which is reported (1978) 68 Cr.App.R. 18. A full account of the proceedings is to be found in L. Kennedy, Wicked Beyond Belief, Granada 1980, and there is a discussion of some of the legal issues by Lord Devlin, The Judge (1980), p. 148 el, seq.

⁹¹ (1974) 59 Cr.App.R. 221, following Birtles (1969) 53 Cr.App.R. 469. The accomplice in question had a picaresque history of involvement in Irish nationalist affairs which concluded shortly after his acquittal when he was found murdered. For a discussion of the issues in the American context see the note “A Prosecutor's Duty to Disclose Promises of Favourable Treatment made to Witnesses for the Prosecution” (1981) 94 Harv.L.R. 887. The matter is discussed, but not really resolved, in the Attorney-General's Guidelines; Disclosure of Information to the Defence in Cases to be Tried on Indictment (1982) 74 Cr.App.R. 302.

⁹² This is echoed in the confidential circular from the Home Secretary to Chief Officers of Police (1969) 19 N.L.J. 513, para. 4 of which provides that “The police must not embark on a course which will constrain them to withhold information from or mislead a court in order to protect an informant.”

⁹³ It is repotted that in the trial of 14 Irish terrorists, who were convicted on the evidence of a former accomplice who had been granted immunity, the trial judge Murray J. was highly critical of the fact that he was uninformed about these matters by the Crown: The Times, 12 April 1983.

⁹⁴ 7306/75, 7 Reports, 115. The Supreme Court of the United States has held that due process is violated by an undisclosed agreement for leniency with prosecution witnesses: Giglio v. U.S., 405 U.S. 150 (1971). Art, 6(1) of the European Convention provides that “a person charged with criminal offences has the right to examine witnesses against him and to obtain the attendance and examination of witnesses on his behalf under the same conditions as witnesses against him.” This raises the possibility that a witness for the defence may some day ask for immunity. An accused who offered money in exchange for evidence (as the state sometimes does) would run the risk of a prosecution for perverting the course of justice.

⁹⁵ (1977) 66 Cr.App.R. 122, followed in Davies and Gorman (1978) 68 Cr.App.R. 319. The practice of rewarding informants is far from new. As Darling J. said in James and Sharman (1913) 9 Cr.App.R. 142, “it is expedient that there should not be [honour among thieves.]”

⁹⁶ (1980) 71 Cr.App.R. 296.

⁹⁷ (1981) 3 Cr.App.R.(S) 258.

² See Woods [1976] Crim.L.R. 112. According to Archbold, para. 4–125, “In Potter, September 15, 1977, C.A. (unrep.), the court observed that the unusual practice (sentencing before the accomplice gives evidence), is not obligatory and whether it is followed depends entirely upon the circumstances of the case.”

⁴ The Times, 20 May 1983. Precisely the same problem has arisen, coincidentally, in New Zealand where the Court of Appeal came down in favour of openness; Broadcasting Corporation of N.Z. v. Att.-Gen. [1982] 1 N.Z.L.R. 120; see J. Caldwell [1982] 6 Crim.L.J. 372.

And Sir Elwyn Jones, “The Office of the Attorney-General” (1969) 27 C.L.J. 43, 50; B. M. Dickens, “The Attorney-General's Consent to Prosecutions” (1972) 35 M.L.R. 347; B. M. Dickens “The Prosecuting Roles of the Attorney-General and the Director of Public Prosecutions” [1974] P.L. 50. The leading work in the area is J. LL. J. Edwards, The Law Officers of the Crown (1964), Chap. 11, where the history of the development of the conventions is described.

⁷ The current position is described by the Prime Minister in her statement to the House of Commons, H.C.Deb., Col. 974, col. 407 (21 November 1979). See also the directive given to the Director General of the Security Service by the then Home Secretary, Sir D. Maxwell-Fyfe, in 1952, reproduced in the Denning Report, Cmnd, 2152 (1963), para. 238.

⁹ See the House of Commons First Report from the Liasion Committee, The Select Committee System, H.C. 92 (1982–83), para. 25, which claims that the work of the security services falls within the ambit of the departmental committees for scrutiny purposes.

¹⁰ The Government excluded the Lord Chancellor's Department and the Law Officers' Department from the scrutiny of the Home Affairs Select Committee, whereas the Procedure Committee had recommended their inclusion. H.C.Deb., Vol. 969, col. 38 (25 June 1979).

¹¹ See the Written Question by Mr. C. Price M.P., asking how many “resident informers” had been employed by the Metropolitan Police since 1 January 1979, and how many successful prosecutions had resulted from information supplied by persons in custody. The answer (18) was conveyed in a private letter from Lord Elton dated 21 June 1982. The reply to the second question was that it was impossible to provide the answer “without disproportionate cost.” I am grateful to Mr. Price for permitting me to see the letter.

¹⁵ See J. D. Heydon, “Statutory Restrictions on the Privilege Against Self-Incrimination” (1971) 87 L.Q.R. 214. The most recent example of legislative intervention in this area is in the Supreme Court Act 1980, s.72, enacted to circumvent the decision of the House of Lords in Rank Film Distributors Ltd. v. Video Information Centre [1982] A.C. 380.

¹⁶ The anonymity customarily given to the witness/victim in blackmail cases is another, and perhaps more important, inducement to such persons to come forward; see R. v. Socialist Worker Printers and Publishers Ltd., ex p. Attorney-General [1975] Q.B. 637.

¹⁷ See Parrott (1913) 8 Cr.App.R. 186, 192; Britten [1969] 1 W.L.R. 151, 153; [1969] 1 All E.R. 517, 518; Sutch [1975] 2 N.Z.L.R. 1, which hold that the expression “enemy” includes a potential enemy, at least for the purposes of the Official Secrets Acts.

¹⁸ Reported in The Times, 12 April 1983. Bennett was undoubtedly one of the “converted terrorists” referred to by the Chief Constable of the Royal Ulster Constabulary in his Annual Report (1982), where the use of immunity from prosecution as a tactic against terrorists in Northern Ireland is acknowledged to be on the increase. According to one report, 80 people have been convicted on the strength of informer evidence, and 200 people are on remand awaiting trial (Observer, 17 July 1983). Thirty-five people were convicted as a result of evidence given by Christopher Black, whose 10-year sentence was remitted, and who was granted immunity for his own part in serious crimes (The Times, 5 August 1983). 28 further people have been arrested and charged in Belfast on the strength of evidence of Robert Lean, who has been granted complete immunity from prosecution. The Times, 12, 13 September, 1983.
