Cross-examination is a typical element of common-law jurisdictions. In international arbitration, it is probably the core of every hearing, and many times the deciding factor when resolving a dispute.
That is why cross-examinations are reserved for the most experienced lawyers of each party.
Antuña has fifteen years of experience in examining experts. Moreover, in Investor-State arbitration, in the last five years alone, he set a world record of 42 cross-examinations (28 quantum experts, seven regulatory experts and seven witnesses).
In international arbitration, stakes are high, and counting with the best of the best in every field and with complementary teams is a priority. That is why co-counseling between several top law firms for each side is commonplace.
