Arguments of the parties
54
In their first ground, directed against paragraphs 35 to 63 of the judgment under appeal, the appellants complain that the General Court erred in law by holding that the refusal by the Hearing Officer to organise an in camera hearing during the administrative procedure had not infringed their right to be heard.
55
They argue that such a refusal is a breach of the procedural right to effectively and thoroughly make their views known on the facts both in writing and orally at a hearing, a right which applies at the stage of the administrative procedure. The Commission must grant a request for an in camera hearing especially when, as in this case, first, the company concerned is seeking to challenge the finding of its decisive influence over its subsidiary and, second, the very existence of this company would be endangered by a hearing in the presence of other companies which were also being prosecuted.
56
The appellants submit that, although the General Court, following the Commission, weighed up the interests, namely, on the one hand, that of the companies whose confidential information was not to be disclosed and, on the other hand, that of the other undertakings to be able to defend themselves against any possible inculpatory evidence, it has, in this case, carried out a wholly disproportionate assessment of those interests to the detriment of the appellants.
57
According to the appellants, since the administrative procedure could have resulted in a different outcome if they had been able to present, in an in camera hearing, their arguments on Degussa’s role, the General Court should have annulled the decision at issue.
58
By holding, in paragraph 53 of the judgment under appeal, that that argument was not such as to relieve the appellants of their liability, the General Court infringed the ‘prohibition of anticipatory assessment of evidence’ and relied on the wrong evidence, leading it to commit an error of assessment concerning the probative value of those arguments.
59
The Commission contends that that ground should be dismissed either as inadmissible in so far as, by that ground, the appellants are seeking to challenge the General Court’s factual findings and its assessment of the evidence or, in any event, as unfounded, since the appellants had sufficient opportunity during the administrative procedure, to present their views regarding Degussa’s role in the cartel. In that regard, the Commission also argues that it is required to allow any company likely to be inculpated during a hearing to be present so that, first, it may take note of evidence which the Commission could use as the basis for additional objections and, second, it may defend itself.
Findings of the Court
60
By the first ground of appeal, the appellants criticise the General Court for concluding, in paragraph 63 of the judgment under appeal, that the Commission and the Hearing Officer took sufficient account of the need to respect their right to be heard when they refused to grant their request that an in camera hearing be organised, given the evidence that the appellant intended to adduce at such a hearing regarding SKW’s position in relation to Degussa.
61
As a preliminary point, and as is clear from paragraph 56 above, it should be noted that the appellants do not dispute that, as the General Court held in paragraph 39 of the judgment under appeal, it is for the Hearing Officer, when he has to assess whether or not to hold a hearing in camera, to reconcile the protection of the rights of the defence of the undertaking prosecuted for an alleged breach of the EU competition rules against the legitimate interest of third parties, persons or companies who provided information or documents related to the alleged infringement to have their business secrets and other confidential information protected.
62
Therefore, the complaint, in the context of the present ground, relates only to the manner in which the General Court weighed up the interests at issue.
63
In that regard, paragraph 62 of the judgment under appeal states as follows:
‘In conclusion, it should be noted that the appellants seem to disregard the fact that their arguments regarding Degussa’s role in the cartel, after the sale of SKW’s entire capital, and their request that that argument not be brought to Degussa’s attention, required a reconciliation of the requirements arising from the rights of the defence of the appellants and those of Degussa, and a weighing up of the respective interests of those undertakings. The facts set out in paragraphs 24 to 32 [of the judgment under appeal] show that the Hearing Officer undertook this weighing up only after hearing the appellants’ explanations as to the content of that argument and its alleged importance to their defence. It appears, moreover, from the considerations set out above that the Hearing Officer correctly came to the conclusion that he was not entitled to give priority to the protection of the [appellants’] rights of defence and therefore to allow the infringement of Degussa’s similar rights …’
64
It follows from paragraph 62 of the judgment under appeal that, in the weighing of the interests involved, the General Court held, in essence, that the appellants’ rights of defence cannot take priority over those of Degussa. In that regard, in paragraphs 58 and 59 of the judgment under appeal, it held that in order to ensure that Degussa’s rights of defence were respected, Degussa had to be in a position, at the hearing, to take immediate note of the accusations concerning it which might be raised by the appellants, and to respond to them orally.
65
It follows from paragraph 55 of the judgment and paragraphs 9 and 10 above that the argument that the appellants wished to put forward in camera concerned the role of Degussa for the period following its sale of SKW to SKW Holding. Degussa has not been the subject of Commission proceedings in respect of that period, either at the time the hearing took place or subsequently.
66
Accordingly, it must be held that, in refusing to grant the appellants’ request to hold an in camera hearing, the Hearing Officer took into account Degussa’s rights of defence, even though the latter could not rely on those rights due to the fact that it was a third party to the proceedings in respect of that period.
67
In that regard, the fact that some of the evidence communicated to the Commission, were it to have granted the request for an in camera hearing, might have subsequently led it to hold Degussa liable for the infringement concerned for a longer period than that originally considered is irrelevant, since, in any event and as noted by the Advocate General in point 60 of his Opinion, the Commission would have been required, in such circumstances, to issue Degussa with a supplementary statement of objections so as to enable that company to present its observations on that evidence.
68
Accordingly, the General Court erred in law and infringed the appellants’ right to be heard, by holding that the Hearing Officer could refuse to hold an in camera hearing on the grounds that such a hearing could have harmed Degussa’s rights of defence.
69
However, it is the Court’s settled case-law that an infringement of the rights of the defence results in the annulment of the contested measure only if, without such an irregularity, the outcome of the procedure might have been different (see, to that effect, judgment of
3 July 2014 in
Kamino International Logistics and Datema Hellmann Worldwide Logistics
, C‑129/13 and C‑130/13, EU:C:2014:2041, paragraph 79
and the case-law cited), which it is for the undertaking concerned to show (see, to that effect, judgment of
29 June 2006 in
SGL Carbon v Commission
, C‑308/04 P, EU:C:2006:433, paragraph 98
).
70
In that regard, it should be noted that, in paragraph 53 of the judgment under appeal, the General Court found that the appellants’ assertions as to Degussa’s influence over SKW’s conduct, even if true, were irrelevant to the question of their liability for the infringement at issue.
71
The appellants dispute this finding, arguing that evidence of Degussa’s continued control over SKW after selling it to SKW Holding was quite likely to call into question Degussa’s decisive influence over SKW, inter alia, given the fact that SKW Holding was only an outside financial investor in the branch which acquired a commercially specialised chemical undertaking.
72
That argument cannot be accepted. As is apparent, in essence, from paragraphs 43, 119 and 120 of the judgment under appeal, the General Court found, in its assessment of the facts, that imputing liability for the infringement in question to SKW Holding could, in any event, be grounded on several factors which were, according to the General Court, by themselves sufficient as a basis for the conclusion that SKW Holding exercised decisive influence over SKW. In the light of that finding, the General Court was entitled to conclude, without erring in law, in particular in paragraphs 48, 49 and 52 of the judgment under appeal, to which it refers in paragraph 53 thereof, that, in order to challenge the attribution of liability, SKW Holding had to demonstrate that it did not itself exercise such influence, so that the question of whether another entity, such as Degussa, exercised decisive influence was not relevant.
73
Inasmuch as the appellants also claim that the General Court infringed the ‘prohibition of anticipatory assessment of evidence’, their argument cannot succeed. By finding that the appellants’ claims as to Degussa’s influence over SKW’s conduct, even if true, were irrelevant as to the question of their liability for the infringement at issue, the General Court did not carry out an anticipatory assessment of evidence, but merely rejected their argument concerning Degussa’s influence over SKW’s conduct, even assuming, for the appellants’ benefit, that that effect were established.
74
Moreover, it should be noted that, in paragraphs 214 to 228 of the judgment under appeal to which paragraph 56 of that judgment refers, the General Court refused to uphold the appellants’ plea alleging that the Commission unlawfully refused to acknowledge that there were extenuating circumstances, which they, as is clear from paragraph 53 above, sought to elaborate in camera.
75
Consequently, the appellants have failed to show that the proceedings against them could have led, in the absence of the irregularity, to a different result.
76
In addition, it is apparent from paragraphs 31, 33 and 62 of the judgment under appeal, the tenor of which has been set out in paragraph 15 above, that, after the conclusion of a new supply contract between SKW and Degussa, that is to say, when the appellants no longer had any difficulties in submitting their arguments on Degussa’s role, they were able to submit written observations to the Commission.
77
It follows that the first ground of appeal must be rejected.
78
It follows from all the foregoing that the appeal must be dismissed in its entirety.
