Let's analyze each clause: 1. Details in respect of the information, available to or held by it, reduced in an electronic form: This is information that public authorities are obligated to proactively maintain and, if possible, disseminate under Section 4(1)(a) and 4(4). It is not an exemption. 2. Information which has been expressly forbidden to be published by any court of law or tribunal or the disclosure of which may constitute contempt of court: This is a valid exemption under Section 8(1) (b). 3. Provide reasons for its administrative or quasi-judicial decisions to the affected person: This is an obligation of the public authority under Section 4(1)(d), not an exemption from providing other information. 4. Information which would impede the process of investigation or apprehension or prosecution of offenders: This is a valid exemption under Section 8(1)(h).
