| Shvidler v Secretary of State for Foreign, Commonwealth and Development Affairs [2025] UKSC 30 |
Explains the role of a first-instance court in assessing proportionality: the court must make its own assessment but should attach special weight to primary decision-makers with institutional competence (e.g., national security). |
The Court applied the principles in Shvidler to confirm that it should make its own proportionality assessment on appeal, while respecting the margin and special weight due to the executive on national security matters. |
| AXA General Insurance Ltd v HM Advocate [2011] UKSC 46 |
Summarises A1P1: existence of possessions, interference, classification as deprivation or control of use, and the fair balance test (lawfulness, legitimate aim, proportionality, margin of appreciation). |
The Court used AXA as an authoritative statement of the A1P1 framework and the threefold analysis that guides whether an interference breaches A1P1. |
| Sporrong and Lönnroth v Sweden (1982) 5 EHRR 35 |
Analysed A1P1 as comprising peaceful enjoyment, deprivation, and control of use; emphasises fair balance and margin of appreciation. |
Referred to via AXA to underline the structure of A1P1 analysis the Court applied to the facts. |
| James v United Kingdom (1986) 8 EHRR 123 |
Confirms that deprivation may arise even where title did not vest in the State and stresses the need for compensation reasonably related to value except where public interest justifies less. |
Used to demonstrate that transfer to a third party pursuant to statute can constitute deprivation and to explain standards for compensation. |
| R (Mott) v Environment Agency [2018] UKSC 10 |
Summarises Strasbourg jurisprudence on deprivation vs control of use and that deprivation normally requires compensation though the distinction is not always clear-cut. |
Cited to support the proposition that classification is significant but not determinative and to inform the proportionality assessment in this context. |
| Trailer and Marine (Leven) Ltd v Secretary of State for the Environment, Food and Rural Affairs [2004] EWCA Civ 1580 |
Reviewed authorities on distinction between taking/deprivation and control of use. |
Referenced as part of the lineage of authority guiding classification and compensation principles under A1P1. |
| AGOSI v United Kingdom (1987) 9 EHRR 1 |
Example where forfeiture in enforcement of criminal prohibition was treated as control of use though it involved deprivation; shows context can recharacterise measures. |
Used as an illustration that an apparent deprivation may be a control of use when seen in its proper context. |
| R v Secretary of State for Health, ex parte Eastside Cheese Co [1999] 3 CMLR 123 |
Court must look behind appearances and investigate the realities of the situation; availability of compensation is relevant to classification. |
Cited to justify examining substance over form when deciding whether a measure is a deprivation and to note the relevance of compensation availability. |
| Holy Monasteries v Greece (1995) 20 EHRR 1 |
"The taking of property without payment of an amount reasonably related to its value will normally constitute a disproportionate interference" — total lack of compensation only in exceptional circumstances. |
Applied to underline that compensation reasonably related to value is ordinarily required but that exceptions may exist; informed the Court's proportionality inquiry. |
| R (SRM Global Master Fund LP) v Treasury Commissioners [2009] EWCA Civ 788 |
Sets out three guiding principles for compensation claims after state intervention: fair balance between public interest and private right, proportionality, and margin of appreciation. |
Referred to for the framework that proportionality normally leads to compensation related to value, but the margin of appreciation can modify that outcome depending on context. |
| Lithgow and Others v United Kingdom (Series A no. 102) |
Explains that legitimate public interest objectives may call for less than full market value compensation in some contexts. |
Used as authority for the proposition that full market-value compensation is not an absolute requirement under A1P1. |
| Vistinš v Latvia (2014) 58 EHRR 4 |
Confirms that compensation terms are material to the fair balance and that where expropriation occurs there should be a procedure ensuring overall assessment, including compensation normally based on value at the date ownership was lost. |
Referred to for the procedural requirement to ensure an overall assessment of compensation and for the principle that compensation normally reflects the property's value at the date of loss; the Court treated it as consistent with other authorities. |
| Osmanyan and Amiraghyan v Armenia (Application No. 71306/11) |
Found violation where expropriation deprived applicants of their means of subsistence and domestic courts had not taken that into account; shows market value may be insufficient in particular circumstances. |
The Court of Appeal treated Osmanyan as fact-specific (mainly about loss of livelihood) and not helpful to the Appellants' case on these facts. |
| Lallement v France (no. 46044/99) |
Referenced for the proposition that compensation must, in some cases, reflect loss of livelihood as part of proportionality. |
Cited within discussion of Osmanyan to illustrate circumstances where market-value compensation may be inadequate. |
| Bank Mellat v HM Treasury (No 2) [2013] UKSC 39 |
Sets out the four-stage proportionality test used in domestic proportionality assessments (importance of objective; rational connection; less intrusive measures; fair balance). |
Adopted as the structured test the Court used to consider proportionality in the A1P1 context, and incorporated into the Court's analysis. |
| In Re Recovery of Medical Costs for Asbestos Diseases (Wales) Bill [2015] UKSC 3 |
Discussed where in the proportionality test the "manifestly without reasonable foundation" (MWRF) concept applies. |
The Court noted that subsequent authority has developed the approach, and treated aspects of this case as superseded by later guidance on margin of judgment. |
| Adriatic Land 5 Ltd v Long Leaseholders at Hippersley Point [2025] EWCA Civ 856 |
Explains that the correct question is what margin of discretion should be afforded given the nature of the legislation; in areas like national security a wide margin may apply and the "manifestly without reasonable foundation" formulation may be appropriate. |
Relied on to justify affording a wide margin of judgment in national security contexts when performing proportionality assessments. |
| R (SC) v Secretary of State for Work and Pensions [2021] UKSC 26 |
Indicates that absence of parliamentary consideration of a specific issue is not necessarily a factor against the executive in Convention rights assessment. |
Used to support the Court's view that the absence of a parliamentary compensation scheme is not determinative against the statutory scheme's compatibility with A1P1. |
| R (Elan-Cane) v Secretary of State for the Home Department [2021] UKSC 56 |
Domestic courts should follow Strasbourg jurisprudence and should not develop Convention law beyond what can be supported by Strasbourg authority. |
Invoked to caution that the domestic court should not extend Convention protections beyond what the European Court of Human Rights jurisprudence supports. |
