Lead Concurrent Sentence Must Reflect Overall Criminality; “No Separate Penalty” Wrong for Serious Weapon Possession in Unduly Lenient Sentence References

1) Introduction

R v Garner ([2026] EWCA Crim 176) is a decision of the Court of Appeal (Criminal Division) on an application by His Majesty’s Solicitor General under section 36 of the Criminal Justice Act 1988 (an “unduly lenient sentence” reference). The respondent (“the offender”), aged 74, had pleaded guilty to:

  • Aggravated burglary (Theft Act 1968, s.10(1))
  • Possessing an imitation firearm with intent to cause fear of violence (Firearms Act 1968, s.16A)
  • Wounding with intent (Offences Against the Person Act 1861, s.18)
  • Having an article with a blade or point (Criminal Justice Act 1988, s.139(1))

The offending involved a targeted attack at the victim’s home, use and discharge of an air pistol presented as a firearm, and repeated violence with an axe causing injury and acute fear. The trial judge imposed a total of 4 years’ imprisonment, largely by selecting a reduced categorisation and a low within-range figure for the lead offence, and by imposing no separate penalty for the weapon possession counts.

The key issues for the Court of Appeal were:

  • Whether the overall sentence fell outside the range reasonably open to the sentencing judge (i.e., was “unduly lenient”).
  • Whether the judge was entitled to treat the offender’s apparent confusion/out-of-character conduct as reducing culpability categorisation.
  • How totality should be reflected where several serious offences are sentenced concurrently.
  • Whether “no separate penalty” was permissible for the weapon counts on these facts.

2) Summary of the Judgment

The Court of Appeal granted leave and held the sentence was unduly lenient. While it accepted the sentencing judge was entitled to place the aggravated burglary in category 1B (rather than 1A), it found the judge set the post-trial “notional” sentence too low within the 1B range and failed properly to ensure the lead sentence reflected the overall gravity of the entire episode (including other serious concurrent offences).

The court also held it was wrong in principle to impose no separate penalty for the two weapon-related offences, which were serious in their own right (even though the resulting sentences should be concurrent).

Substituted sentences (all concurrent) produced a new total of 6 years’ imprisonment:

  • Count 1 (aggravated burglary): 6 years (derived from a 9-year notional after-trial sentence with full guilty plea credit)
  • Count 2 (imitation firearm, intent to cause fear): 2 years
  • Count 3 (s.18 wounding with intent): 3 years (unchanged)
  • Count 4 (bladed article): 18 months

3) Analysis

3.1 Precedents Cited

The court relied on the established section 36 framework as summarised in Attorney-General's Reference (Egan) [2022] EWCA Crim 1751; [2023] 2 Cr App R(S) 16 (at [3–6] of that case, quoted in substance at [25] of the present judgment). That authority reiterates four controlling propositions:

  1. The sentencing judge is usually best placed to weigh competing factors.
  2. A sentence is “unduly lenient” only if it falls outside the range of reasonable sentences.
  3. Leave is granted only exceptionally and not in borderline cases.
  4. Section 36 targets “gross error”, not mere differences of view.

Influence on the outcome: The Court of Appeal expressly applied this restrained supervisory approach. It did not simply re-sentence from scratch, and it declined to accept the Solicitor General’s arguments “in their entirety” ([27]). Notably, it deferred to the sentencing judge’s evaluative judgment on categorisation (accepting 1B), while still finding “gross error” in how the sentence was fixed within the range and how totality and ancillary counts were treated.

3.2 Legal Reasoning

(a) Categorisation and “state of mind”

A central complaint was that the judge reduced culpability categorisation for aggravated burglary from A to B due to apparent confusion/out-of-character conduct, without explicit reliance on the guideline for Sentencing Offenders with Mental Disorders, Developmental Disorders or Neurological Impairments. The Court of Appeal did not accept the Solicitor General’s position that culpability must be A; instead it held the judge was entitled to place the offence in category 1B ([27]).

However, the key error was not the categorisation itself; it was the selection of a bottom-of-range notional sentence (6 years after trial) for a crime involving serious violence in a dwelling with an axe and an imitation firearm, and the failure to set the lead count so that it properly captured the overall gravity of the criminal episode ([27]).

(b) Totality where sentences are concurrent

The court’s reasoning is doctrinally important: even where it is correct to make other sentences concurrent, the judge must still ensure the lead sentence reflects the overall criminality. The Court of Appeal stated that, beyond the lead offence “by itself”, account had to be taken of “the fact there were other offences on which sentence had to be passed” and that the lead sentence “had to be sufficient to reflect the overall gravity of the offending” ([27]).

This explains the move from a 6-year post-trial notional figure (as chosen below) to 9 years post-trial for the aggravated burglary ([30]), even though concurrency remained appropriate.

(c) “No separate penalty” and separate sentencing for serious ancillary counts

The court held it was wrong in principle to impose “no separate penalty” on:

  • Count 2 (imitation firearm with intent to cause fear of violence)
  • Count 4 (possession of a bladed article)

The point is not formalism. The court treated these as “serious examples” that merited custodial sentences in their own right ([28]), even though the proper application of totality meant they would be concurrent. The court therefore imposed 2 years on count 2 and 18 months on count 4 ([29]).

The decision signals a practical limit on “no separate penalty”: it should not be used to erase the penal significance of distinct, serious offences merely because they arise from the same incident and concurrency is inevitable.

(d) Guilty plea credit

The Solicitor General raised a technical criticism about full credit on count 3 (s.18), but the Court of Appeal treated it as immaterial to the overall term and confirmed full one-third credit was appropriate on the lead count ([30]).

3.3 Impact

  • Concurrent sentencing discipline: Sentencers should expect appellate correction if, after choosing concurrency, they fail to adjust the lead sentence to reflect the combined seriousness of multiple grave offences.
  • Restriction on “no separate penalty”: For serious weapon possession offences (especially where a weapon is used, discharged, or integral to fear/violence), “no separate penalty” risks being characterised as an error of principle.
  • Section 36 calibration: The case illustrates how the Court of Appeal can simultaneously (i) defer to evaluative judgments like guideline categorisation and (ii) still find undue leniency based on within-range selection and totality failures.

4) Complex Concepts Simplified

  • “Unduly lenient” (s.36 CJA 1988): Not “too low” in an ordinary sense—only a sentence outside the reasonable range, indicating significant error.
  • Culpability and harm categories: Guideline “boxes” that structure sentencing; categorisation affects the starting point and range.
  • Notional after-trial sentence: The sentence the court would have imposed following conviction after trial, before applying guilty plea reduction.
  • Concurrent sentences: Served at the same time; the total term equals the longest single sentence.
  • Totality: A check that the overall sentence is just and proportionate to the whole offending; concurrency does not remove the need for the lead sentence to reflect the episode’s full gravity.
  • “No separate penalty”: The court records a conviction but imposes no additional punishment for that count. It is generally inappropriate where the count is serious and deserves distinct penal recognition, even if concurrent time results.

5) Conclusion

Garner confirms that in section 36 references the Court of Appeal will respect sentencing discretion on evaluative matters like guideline categorisation, but will intervene where the lead concurrent sentence fails to reflect the overall criminality or where “no separate penalty” is used for serious ancillary offences. The substituted sentence (increasing the total from 4 to 6 years) crystallises a practical rule for sentencers: concurrency is not a reason to under-state the seriousness of distinct offences—either through an artificially low lead term or by suppressing proper sentences on other serious counts.
