Your request
Under the Freedom of Information Act, I am requesting the Zoetis research information you hold in relation to Lenivia and Portela
Our reply
Under Section 43(3) of the Freedom of Information Act 2000, we are entitled to neither confirm nor deny whether we hold the requested information, where doing so would or would be likely to prejudice the commercial interests of a third party under Section 43(2).
Disclosure, or even confirmation of the existence or absence of applications, would be commercially sensitive, as it could reveal confidential product development timelines, applicants’ strategic positioning, or ongoing evaluation processes. This would be likely to prejudice both the applicants’ commercial interests and the integrity of the regulatory process.
We acknowledge the public interest in transparency. However, this is outweighed by the stronger public interest in safeguarding the confidentiality of commercial information and preserving a fair and effective regulatory system. Confirming or denying the existence of information would itself risk undermining these key interests.
Accordingly, we must refuse to confirm or deny whether the requested information is held, relying on the exemption provided by Section 43(3).
