Consecutive Minimum Terms Are Lawful for Multiple Life Sentences: Totality Must Reflect “Additional Criminality” and Ensure Transparent Punishment

1. Introduction

Tanga, R. v concerns an Attorney General’s Reference under section 36 of the Criminal Justice Act 1988 challenging as “unduly lenient” the minimum term fixed for a second murder where the offender was already subject to a life sentence for an earlier murder. The central issue was whether the sentencing judge was wrong not to impose consecutive minimum terms (or, put another way, whether the overall minimum term adequately reflected the separate criminality of the second murder).

The offender, Vitalie Tanga, committed two murders: Alfred Mattox (10 May 2021) and, later, Tajinder Kular (29–30 September 2022) while on remand in HMP Birmingham. He received a life sentence for Mattox (minimum term 25 years, after remand credit) and later a life sentence for Kular with a minimum term of 26 years and 4 months (later expressed in the judgment as an overall structure producing an “uplift” in practical release terms).

The Court of Appeal (Criminal Division) (Dingemans LJ, Senior President of Tribunals, giving the judgment) granted leave and ultimately increased the minimum term for the Kular murder from 27 years and 6 months to 32 years and 6 months, on the basis that the sentence imposed was unduly lenient in its overall effect.

2. Summary of the Judgment

  • The Court clarified that it is legally possible to impose consecutive indeterminate sentences, including life sentences with minimum terms, and that any assumption to the contrary (sometimes associated with Stewart) is incorrect.
  • The Court held the sentencing judge was entitled to structure the second life sentence as running from the date of imposition (i.e., without expressly making the second minimum term consecutive), but the judge still had to ensure the overall effect delivered just punishment for both murders (totality and proportionality).
  • In this case, the practical “uplift” in the earliest possible release date was only five years and two months, which the Court found did not fairly reflect the additional criminality of a second murder, particularly one committed in custody.
  • The Court concluded that for the Kular murder alone, a minimum term of at least 17 years would have been required before any totality adjustment. To achieve transparency and fair overall effect, the Court substituted a higher minimum term: 32 years and 6 months.

3. Analysis

3.1 Precedents Cited

R v Stewart [2022] EWCA Crim 1063; [2022] 4 WLR 86

Stewart was central because the sentencing judge was referred to it and attempted to emulate its approach to “uplifting” a minimum term to reflect additional offending. In Stewart the Court emphasised that the sentencing focus is the offence before the court, though an adjustment may be made to achieve just punishment and proportionality for the offender’s overall criminality.

However, this judgment exposes two critical limits to relying on Stewart:

  • The statement in Stewart that “it is not possible for a life sentence to be ordered to run consecutively to another life sentence” was identified as obiter and inconsistent with guidance and statutory machinery (notably the ability to direct otherwise under section 384).
  • The Court warned that comparing the numerical uplift in Stewart can be misleading because its proportionality was materially affected by the offender’s age (he would not be considered for release until about 96), a contextual factor absent here.

R v O'Brien [2006] EWCA Crim 1741; [2007] 1 WLR 833

The Court relied on O'Brien (especially [57]) for the proposition that no rule of law prevents consecutive indeterminate sentences. This authority underpinned the Court’s correction of any notion that consecutive life/minimum term structuring is impermissible.

R v Hills [2008] EWCA Crim 1871

Hills supported the broader proposition that courts can lawfully structure sentences so that a determinate sentence runs consecutively to a life sentence, reinforcing that consecutive structuring is not prohibited in principle.

Attorney General's Reference (No 4 of 1989) 11 Cr App R(S) 517

This authority set the controlling test for intervention: the Court should interfere only where the sentencing judge has gone wrong and the sentence is not merely lenient but unduly lenient. Even then, the Court retains a discretion whether to increase sentence.

Sentencing Principles, Procedure and Practice 2025, 5th edition (commentary at paragraph A4-669)

While not a “precedent” in the strict sense, the Court treated the editors’ analysis as a significant indicator of modern sentencing policy: the historic practice of “inflating” concurrent minimum terms for practical effect can reduce transparency and may create downstream problems (including in the event of changes to release regimes). The commentary supports explicit consecutive minimum terms where appropriate.

3.2 Legal Reasoning

(a) The statutory and guideline framework

  • Murder carries a mandatory life sentence (section 1 of the Murder (Abolition of Death Penalty) Act 1965).
  • The court must fix either a whole life order or a minimum term under the Sentencing Act 2020, applying Schedule 21:
    • Default starting point (adult cases outside the specified higher categories): 15 years (paragraph 5).
    • Then adjust for aggravating/mitigating factors (paragraph 7).
  • The totality guideline governs sentencing where an offender is already serving a sentence. It indicates that offences committed in prison will ordinarily justify consecutive treatment, while also noting it is “generally undesirable” for an indeterminate sentence to be consecutive—yet expressly recognising that it can be done where necessary.
  • Section 384 of the Sentencing Code (as referenced by the Court) provides that a Crown Court sentence takes effect immediately unless the court directs otherwise—this is the mechanism that allows explicit consecutive directions.

(b) The Court’s five “propositions of law”

A key jurisprudential contribution of the judgment is the Court’s explicit consolidation of the legal position into five propositions:

  1. A court can impose consecutive indeterminate sentences (section 384 and O'Brien at [57]).
  2. A court can impose a determinate sentence consecutively to an indeterminate sentence with a minimum term.
  3. A court can sentence an offender already serving life to a second life sentence and set either a consecutive minimum term or a concurrent minimum term.
  4. If the second minimum term is not made consecutive, the court must still set a minimum term that reflects overall criminality.
  5. Whatever the structure, the court must ensure the overall effect achieves just punishment and is proportionate, taking account of time served.

(c) Why the original sentence was “unduly lenient”

The Court drew a sharp distinction between (i) the legality of the judge’s approach to structuring the sentence and (ii) the adequacy of the overall effect. Although the judge could lawfully avoid specifying consecutivity, the resulting practical increase to the release horizon (about five years and two months) failed, for this offender (aged 42), to reflect the additional criminality of:

  • a second murder,
  • committed in custody,
  • with prior convictions including a previous murder,
  • and while he had been released under investigation in relation to the earlier homicide.

The Court also rejected any simplistic “addition” of minimum terms (totality makes that impermissible), but held that some materially greater extension was required. It therefore adopted a transparent, effect-based correction: identifying that the second murder would require at least 17 years (pre-totality), and then adding ten years (in practical effect) to the outstanding part of the first minimum term to reflect totality and separate criminality. The result was substitution of 32 years and 6 months.

(d) Attorney General’s Reference discipline

The Court explicitly applied the restraint mandated by Attorney General's Reference (No 4 of 1989) 11 Cr App R(S) 517: intervention is justified only for sentences outside the range reasonably open to the judge. Here, the deficiency lay not in a modest uplift, but in an uplift that the Court considered failed to represent the second murder as a distinct and grave wrong.

3.3 Impact

  • Clarification of law: The judgment corrects the practical misunderstanding that consecutive life/minimum term structuring is impossible. By treating the contrary statement in R v Stewart [2022] EWCA Crim 1063; [2022] 4 WLR 86 as obiter and inconsistent with the framework, it reduces the risk of systemic sentencing error in multiple murder cases.
  • Greater transparency in sentencing multiple murders: The Court endorses (and operationalises) the idea that sentencing should make clear what extra punishment flows from the later murder, rather than obscuring it in a small uplift to an overall minimum term.
  • Custody murders treated as especially serious: The Court emphasised that commission of murder in prison is “particularly important,” likely encouraging future courts to regard prison-context killings as strongly pointing to consecutive effect or substantial overall increases.
  • Warnings against mechanical reliance on “uplift comparisons”: The Court’s discussion of Stewart signals that sentencing cannot safely be benchmarked solely by the numerical size of an uplift; proportionality must be grounded in offender-specific realities (including age and the real prospect of release).
  • Release-regime resilience: By favouring explicit, principled reflection of additional criminality, the approach reduces the risk that future changes to release regimes create unintended outcomes (a concern flagged in the cited textbook commentary).

4. Complex Concepts Simplified

Life sentence and minimum term
A life sentence means the offender remains liable to detention for life, but may be considered for release after serving the court-fixed minimum term (tariff). Release is not automatic; it depends on risk and Parole Board decisions.
Whole life order
A whole life order means there is no minimum term after which early release provisions apply—effectively no prospect of release except in exceptional circumstances.
Concurrent vs consecutive minimum terms
“Concurrent” means the minimum terms effectively run together from the date imposed. “Consecutive” means the second is directed to begin after the first (or after some specified point), increasing the time before the offender can be considered for release.
Totality
A principle ensuring the overall punishment for multiple offences is just and proportionate—neither a mechanical accumulation nor an under-punishment that fails to recognise separate serious wrongdoing.
Unduly lenient
Not merely “a bit low.” It means outside the range of sentences reasonably available to a judge applying correct principles—serious enough to justify appellate intervention.
Obiter
A remark not necessary for the decision. It may be persuasive but is not binding, and can be departed from if inconsistent with law or later analysis.

5. Conclusion

Tanga, R. v establishes a clear and practical rule for multiple murder sentencing: courts can impose consecutive minimum terms for life sentences, and regardless of the chosen structure they must ensure the overall effect reflects additional criminality with transparency and proportionality.

The Court’s intervention underscores that a second murder—especially one committed in prison by an offender already involved in a prior homicide— requires a sentencing outcome that communicates distinct condemnation and produces a commensurate practical impact. The substituted minimum term of 32 years and 6 months operationalises that principle and serves as a caution against using R v Stewart [2022] EWCA Crim 1063; [2022] 4 WLR 86 as a numeric “uplift template” divorced from context.
