ECHR 340 (2013)

Norwegian authorities failed to provide deep sea divers  
with essential information about risks associated with their employers’ use  
of rapid decompression tables  
In today’s Chamber judgment in the case of Vilnes and Others v. Norway (application no. 52806/09),  
which is not final1, the European Court of Human Rights held, by a majority, that there had been:  
a violation of Article 8 (right to respect for private and family life) of the European Convention on  
Human Rights on account of the failure of the Norwegian authorities to ensure that the applicants  
received essential information enabling them to assess the risks to their health and lives resulting  
from the use of rapid decompression tables;  
no violation of Articles 2 (right to life) or 8 as regards the remainder of the applicants’ complaints  
about the authorities’ failure to prevent their health and lives from being put in jeopardy; and  
no violation of Article 3 (prohibition of inhuman or degrading treatment);  
The case concerned former complaints by divers that they are disabled as a result of diving in the  
North Sea for oil companies during the pioneer period of oil exploration (from 1965 to 1990).  
As regards the applicants’ complaints concerning the authorities’ failure to prevent their health and  
lives from being put in jeopardy, the Court considered that the authorities had taken a wide range of  
measures in order to ensure the protection of divers’ safety, thus complying with their positive  
obligations under Articles 2, 3 and 8. However, the Court also found that the authorities had failed to  
comply with their obligation under article 8 to provide access to essential information enabling  
individuals to assess the risks to their health and lives. Indeed, although there had been a lack of  
scientific consensus regarding the long-term effects of decompression sickness, diving companies  
had been allowed to keep their respective diving tables secret merely in order to have a competitive  
advantage over other companies. Therefore, divers had been denied access to essential information  
on rapid decompression times and on the consequence that this could have on their health and  
safety. As a result, they had been unable to fully assess the risks involved and give their informed  
consent.  
This case is of interest because it complements the Court’s case-law on access to information under  
Articles 2 and 8, notably in so far as it establishes an obligation on the authorities to ensure that  
employees receive essential information enabling them to assess occupational risks to their health  
and safety.  
1 Under Articles 43 and 44 of the Convention, this Chamber judgment is not final. During the three-month period following its delivery,  
any party may request that the case be referred to the Grand Chamber of the Court. If such a request is made, a panel of five judges  
considers whether the case deserves further examination. In that event, the Grand Chamber will hear the case and deliver a final  
judgment. If the referral request is refused, the Chamber judgment will become final on that day.  
Once a judgment becomes final, it is transmitted to the Committee of Ministers of the Council of Europe for supervision of its execution.

Principal facts  
The applicants are five Norwegian nationals living in Norway, Dag Vilnes (born in 1949 and living in  
Tønsberg), Magn Håkon Muledal (born in 1953 and living in Førde), Bjørn Anders Nesdal (born in  
1958 and living in Kristiansand), Knut Arvid Nygård (born in 1961 and living in Tananger) and Per  
Arne Jacobsen (born in 1954 and living in Larvik); and, a Swedish national, Mr Lindahl (born in 1942,  
and living in Avaldsnes, Norway) and an Icelandic national, Sigurdur P. Hafsteninsson (born in 1953  
and living in Jersey, United Kingdom).  
They were all former deep sea divers who had taken part in North Sea diving operations for the  
petroleum industry during what was known as the pioneer period (from 1965 to 1990). All alleged  
that they had developed health problems and had become disabled as a result of both bounce  
(short) and saturation (longer duration) diving jobs. Most were still suffering from obstructive lung  
disease, encephalopathy, reduced hearing and Post Traumatic Stress Disorder (PTSD). They  
particularly alleged that shortcuts taken in their working conditions and safety had put their health  
and lives in jeopardy. Dispensation arrangements from safety regulations had often been authorised2  
, such as extending the maximum period of a saturation dive as well as the maximum length of the  
divers’ umbilical (the breathing gas supply). Furthermore, decompression tables used for the return  
of divers to the surface had not been standardised until 1990, allowing oil companies to reduce the  
decompression time, lower their labour costs and have a competitive advantage over other  
companies.  
As a result, most of the applicants had experienced decompression sickness and the bends. Notably,  
Mr Vilnes claimed that he had been involved in an incident when working on board the diving vessel  
Arctic Surveyor in 1977 when he had been exposed to serious decompression sickness causing him  
permanent brain and spinal damage. He further complained of another incident when, working on  
the Tender Comet in 1983, he had experienced earache and severe pain during decompression and  
decided to discontinue a dive. Lastly, the last six applicants also provided detailed accounts of the  
harm caused to them by test diving in which they participated – without their informed consent – in  
Bergen and the Norwegian fjords with NUI AS/Nutec AS (Norsk Undervannsintervensjon – Norwegian  
Underwater Intervention Ltd and Falc Nutec safety company).  
It has been known for some time that the 350 to 400 pioneer divers, including the applicants, had  
developed health problems from diving. Long term studies showed possible connections between  
diving and injuries to the central nervous system; and, in December 2002, a report from an  
independent inquiry (the “Lossius report”) suggested that the State had legal and therefore financial  
liability for the injuries sustained by North Sea divers and recommended that the divers be granted  
compensation. The Government, although not accepting liability from a legal point of view,  
considered that it had a moral and political duty to compensate the divers and a special  
compensation scheme was set up.  
Mr Vilnes has a disability pension and work injury benefits and, under the State compensation  
scheme, has received 3,600,000 Norwegian krone (462,700 euros). The other six applicants each  
receive disability pensions and some of them – like Mr Vilnes – have received compensation from  
the State and the oil companies, Statoil/Hydro. In February 2005 Mr Vilnes brought proceedings  
against the State claiming additional compensation and in December 2005 Mr Muledal and the other  
five applicants brought similar claims. All the cases were subsequently joined, the third to seventh  
applicants’ claims being adjourned pending the outcome of the proceedings brought by Mr Muledal.  
Initially, in August 2007, Oslo City Court found for Mr Vilnes and Mr Muledal. Although the State had  
taken all measures that could reasonably be expected to protect divers’ lives (meaning no breach of  
Article 2 of the European Convention), when balancing the various interests (the disturbing number

By the Norwegian Labour Inspection Authority (until April 1978) and subsequently the Petroleum Directorate, the public authorities  
entrusted with supervising and authorising diving operations.  
2
of disabled divers compared to the fact that Norway had become one of the world’s richest nations  
thanks to oil), it found on the whole that it would be reasonable and equitable to make the State  
liable for the damage to divers’ health.  
Later, however, in judgments of November 2008 and October 2009 the High Court and the Supreme  
Court both found against the first and second applicants. As concerned Mr Vilnes’ complaints about  
specific incidents at the diving vessels Arctic Surveyor in 1977 and Tender Comet in 1983 the courts  
found no basis for holding the State responsible on strict liability ground in the absence of a  
sufficiently close connection between the State and the alleged harmful activity. Nor could the State  
be held liable according to the law on employer’s liability having regard to the measures taken by  
the authorities to ensure the adoption of relevant safety regulations backed up by effective  
implementation, inspection and supervision mechanisms.  
Complaints, procedure and composition of the Court  
Relying in particular on Articles 2 (right to life), 3 (prohibition of inhuman and degrading treatment)  
and 8 (right to respect for private life) of the Convention, all the applicants complain that the State  
failed to take appropriate steps to protect deep sea divers’ health and lives when working in the  
North Sea and, as concerned three of the applicants, at testing facilities. They all also allege that the  
State failed to provide them with adequate information about the risks involved in both deep sea  
diving and test diving.  
The application was lodged with the European Court of Human Rights on 24 September 2009.  
Judgment was given by a Chamber of seven judges, composed as follows:  
Nina Vajić (Croatia), President,  
Peer Lorenzen (Denmark),  
Khanlar Hajiyev (Azerbaijan),  
Mirjana Lazarova Trajkovska (“the Former Yugoslav Republic of Macedonia”),  
Julia Laffranque (Estonia),  
Linos-Alexandre Sicilianos (Greece) and,  
Dag Bugge Nordén (Norway), ad hoc Judge,  
and also Søren Nielsen, Section Registrar.  
Decision of the Court  
Articles 2 (right to life) and 8 (right to respect for private and family life)  
As regards the applicants’ general complaints concerning the authorities’ failure to prevent their  
health and lives from being put at risk, the Court mainly agreed with the assessments made by both  
the Supreme Court and the High Court. Notably, it confirmed that the regulatory framework put in  
place by the Norwegian authorities had sought to protect divers’ safety responsibly and that the  
public funded supervision had not been organised in an irresponsible manner.  
The Court then examined Mr Muledal’s, Mr Lindhal’s and Mr Hafsteinsson’s complaints related to  
test diving. Referring to the Supreme Court’s findings, it considered that the divers had been  
sufficiently informed about the test dives, which had been previously approved by the competent  
bodies after a thorough examination according to relevant medical norms and in the light of  
information available at the time. It also found that, by their very nature, the test dives had involved  
certain risks which made it difficult to compare them with other North Sea diving operations.  
Therefore, the Court found that the Norwegian authorities could not be held responsible for any  
violation of Articles 2 and 8 with regards to test diving.  
3
The Court went on to examine Mr Vilnes’ complaints about the incidents which had occurred on the  
diving vessel Arctic Surveyor in 1977 and on the Tender Comet in 1983. Apart from his allegation that  
he had been exposed to serious decompression sickness owing to the use of excessively rapid  
decompression tables, the Court found that Mr Vilnes’ submissions concerning other incidents were  
too vague to determine whether they could be imputable to the Norwegian authorities. Accordingly,  
this part of his complaint was rejected as manifestly ill-founded.  
The Court reiterated that all the applicants had had the possibility to have the merits of their  
compensation claims heard by national courts. Moreover, the Norwegian authorities and Statoil had  
also set up special compensation schemes under which divers had been eligible to apply for  
substantial amounts of compensation, which all seven applicants had done successfully. Therefore,  
by taking a wide range of measures, the Norwegian authorities had put significant effort into  
securing the protection of the divers’ health and safety, thus complying with their obligations under  
both Articles 2 and 8.  
However, the Court found it probable that the applicants’ health had significantly deteriorated as a  
result of decompression sickness. It was also very likely that this had been due to the use of  
excessively rapid decompression tables by diving companies. Indeed, following the standardisation  
of decompression tables by the Petroleum Directorate in 1990, significantly fewer divers had  
suffered from decompression sickness. Therefore, had the Norwegian authorities intervened earlier,  
they probably could have removed what appeared to have been a major cause of excessive risk to  
the applicants’ health and safety.  
Since none of the applicants had been exposed to life-threatening experiences owing to any failure  
on the part of the State, the Court did not analyse the matter in the light of Article 2. However, it  
reiterated the State’s obligation under Article 8 to provide access to essential information enabling  
individuals to assess risks to their health and lives. It found that decompression tables could be  
viewed as a relevant source of information allowing divers to assess the risks to which they could  
have been exposed. Yet neither the Labour Inspection Authority nor the Petroleum Directorate had  
required diving companies to produce their decompression tables in order to assess their safety  
before granting them authorisation to carry out individual diving operations. As a result, diving  
companies had been allowed to keep decompression tables secret and to reduce decompression  
times for competitive purposes.  
Although there had not been a scientific consensus as to the long-term effects of diving, it had also  
been widely acknowledged that decompression tables contained essential information for the  
assessment of health risks within the framework of diving operations. For instance, in a letter of June  
1984 to the Diving Medical Advisory Committee, the Petroleum Directorate had expressed its  
concerns about the difference between the slowest and the fastest decompression tables used in  
the North Sea. However, the authorities had neither informed the applicants as to the possible  
impact of such differences nor told them their concerns as regards their health and safety.  
Moreover, a long period had elapsed until such time as the authorities had required oil companies to  
assume full openness about the decompression tables.  
Considering the authorities’ role in monitoring diving operations and in ensuring their safety, as well  
as the lack of scientific consensus at the time regarding the long-term effect of decompression  
sickness, a very cautious approach should have been adopted. Indeed, the authorities should have  
taken steps to ensure that the applicants had received essential information regarding rapid  
decompression tables, thus enabling them to assess the risks to their health and safety. Had the  
authorities done so, they might have helped to eliminate sooner the use of excessively rapid  
decompression tables as a means for diving companies to promote their own commercial interest  
regardless of the divers’ health and safety. By failing to do so, the Norwegian authorities had not  
fulfilled their obligation to ensure the applicants’ right to respect for their private life, in violation of  
Article 8.  
4
Article 3 (prohibition of inhuman and degrading treatments)  
The Court referred to its previous findings that the authorities’ failure had been confined to a failure  
under Article 8 to provide access to information regarding risks involved in the use of excessively  
rapid decompression tables. Therefore it did not find that there had been a violation of Article 3 in  
this case.  
Just satisfaction (Article 41)  
The court held that Norway was to pay 8,000 euros (EUR) to each applicant in respect of non-  
pecuniary damage, EUR 40,000 to Mr Vilnes in respect of costs and expenses, and EUR 50,000 to Mr  
Muledal, Mr Lindahl, Mr Sigurdur P. Hafsteinsson, Mr Nygård, Mr Nesdal and Mr Jakobsen jointly in  
respect of costs and expenses.
