Questão jurídica principal
Whether mutual assistance to the HCMC under Art. 38 BEHG was permissible despite objections about confidentiality and seriousness of the foreign authority's assurances.
Decisão extraída
Yes. The HCMC is a securities supervisory authority, and there were no reasons to doubt its assurances on confidentiality and limited use of the information.
Fundamentação extraída
The court relied on prior case law and held that the HCMC's written assurances were credible; the cited article and corruption index did not undermine them.
