Baker's research on joint enterprise complicity influenced significantly the outcome of the Supreme Court’s decision on joint enterprise in R. v Jogee and this is acknowledged in a foreword by Lord Toulson in his monograph entitled: Reinterpreting Complicity and Inchoate Participation Offences.

Lord Toulson writes: “I had a copy of the manuscript of this book when examining the issues raised in R v Jogee [2016] UKSC 8, and it was helpful to me. Professor Baker’s arguments on the point, which was of central importance in that case, that foresight is evidence from which intention may be inferred, but no more than evidence, and that secondary liability for a criminal offence requires intent to encourage or assist its perpetration, were well researched and cogent. The same applies to his writing about the need for there to be actual assistance or encouragement, and about the nature of intent, which may be conditional. …”

More recently the New Zealand Court of Appeal adopted Baker's argument that indirect intention exists an independent fault element and is not simply evidence of direct intention.

In the Court of Appeal of New Zealand before French, Miller and Winkelmann J.J. with Winkelman delivering the judgment of the Court, it was said: “[F]oresight of virtually certain consequences can itself be evidence of direct intention.

By this we mean that evidence the defendant foresaw an outcome to some high level of certainty is evidence from which it can be inferred that the person directly intended that outcome.

As Dennis J. Baker, Textbook of Criminal Law (London: Sweet & Maxwell, 2015) says: ‘The grey area is where it can be shown that the defendant at the very least foresaw the consequence as a virtual certainty; but it is not clear whether she directly intended the consequence. In this situation, the jury can use the evidence that [the defendant] foresaw the consequence as virtually certain to infer either direct or indirect intention.’ We are satisfied that such an inference is appropriate in this case. Mr Jury’s knowledge that the tobacco would be used for manufacture, even if that was not an objective Mr Jury wanted or desired for its own sake, is evidence available to support an inference that this consequence was directly intended by him.”

Chief Executive of the New Zealand Customs Service v. Jury [2017] N.Z.C.A. 356 at paras. 86-87.

Coupled with the above, Baker has been quoted by the Supreme Court of Canada in R. v. Ryan [2013] SCC 3 at paragraphs 30; 52; 79 et passim.

He is also quoted in R v Willis (TAW), 2016 MBCA 113 (Court of Appeal — Manitoba); R v Meer, 2015 ABCA 340 (Court of Appeal — Alberta).

His remote harms paper was cited in UNITED STATES OF AMERICA v. DECOSTER (2015) WL 4504795 (C.A.8) (Appellate Brief) United States Court of Appeals, Eighth Circuit.

His monograph on complicity was cited in HKSAR v Chan Kam Shing [2016] HKEC 2715 (Hong Kong, Final Court of Appeal).

His work on omissions is cited by the full court of the High Court of Australia in Burns v. The Queen (2011) 205 A. Crim. R. 240.

In addition, his work has been cited by the Supreme Court of New Zealand in Cullen v The Queen [2015] NZSC 73 and also the New Zealand Court of Appeal in Chief Executive of the New Zealand Customs Service v Jury [2017] NZCA 356 (18 August 2017); Yu v New Zealand Customs Service [2016] NZCA 140; R. v. Dixon [2014] NZCA 329 and in Stepanicic v R [2015] NZCA 35.

In England and Wales he has been cited in Britain in Bauer v DPP [2013] 1 W.L.R. 3617 and in Loake v CPS [2017] EWHC 2855 where Lord Justice Irwin said: “In virtually every case where the defendant proves that he did not know the nature and quality of his act at the time he performed it, then he will not be criminally responsible irrespective of the first limb of the M’Naghten test, because he will lack the mens rea for the alleged offence.

The woman who squeezes her husband's throat believing she is strangling a deadly snake does not have the mens rea for murder, because she lacks the necessary intention to kill or cause really serious harm: Dennis J. Baker, Textbook of Criminal Law (4th Edn by Dennis J. Baker), para 30-016.”

His work on self-defence is quoted repeatedly by the Tasmania Law Reform Institute in its Review of the Law Relating to Self-defence, (ISSUES PAPER NO. 20 NOVEMBER 2014).

His work on homicide is quoted in the Public inquiry into the death of Jean Steven Boucher in Canada in the Report to the Minister of Justice and Attorney General Pubic Fatality Inquiry.

Baker has also given evidence in the Hong Kong Legislative Council to the Panel on Administration of Justice and Legal Services, with respect to prosecution policy and procedure arising from the case of Mr. Chung Yit-tin (archived as Legislative Council Paper No. CB(2)1357/07-08(04).

In 2016, Baker gave expert evidence to the Nuffield Council on Bioethics’ Working Party on Cosmetic Procedures: Ethical Issues.
