In 2013, Electrolux do Brasil S.A ("Electrolux") lodged a damages lawsuit against Whirlpool S.A ("Whirlpool") and Brasmotors S.A ("Brasmotors") 2 due to losses resulting from the acquisition of compressors purchased under artificially high prices as a result of the defendant's participation in an alleged cartel 3. Whirpool and Brasmotors claimed in their Special Appeal that it was impossible to attach copies of the Leniency Agreement signed by a third undertaking 4 to the lawsuit's record, in addition to other documents which justified the initiation of the cartel investigation. According to Justice Marco Aurélio Bellizze, Rapporteur of the Special Appeal before the STJ, the confidentiality initially granted by Leniency Agreements plays a crucial role in effectively enforcing its provisions, both in relation to incentives for collaboration by coauthors and the success of the investigations triggered by the agreement.
