Other contentious corporate matters
- Acted as lead counsel and successfully defended a client in a matter involving amongst others, breach of director’s duties, passing off and conspiracy to injure. Javier obtained a swift victory for the client by obtaining a declaration from the Court that matters were already settled in an agreement, thereby preventing the matter from escalating further. The application for declaration dealt with the novel issue in Singapore of whether a settlement agreement could settle unknown and even fraudulent claims, as well as claims that arose after the date of settlement.
- Acted for Edge Capital Fund SP2 Pte Ltd, an asset management firm in a suit against doctors in Singapore involving the manufacture, supply and storage of mesenchymal stem cells under the new Regulations in the Health Products Act. This case involves tackling novel issues in relation to interpretation and application of the Regulations. The case also involves breach of directors’ duties, breach of contract and misrepresentation.
