- ‘Their ability to anticipate the actions of both counterparties and courts represent tremendous added value.’
- ‘The team led by Mario Ybar has several very strong points that play in its favour. The first is client service. This isn't always the case for international law firms, but they have managed to turn it into a competitive advantage.
