Hi, I'm scott:
I see this was for Delta-Lawyer, but it has been 8 hours: if he comes online and his answer is more responsive, of course, go with him. But maybe I can help otherwise.
First, as you know, we cannot give specific legal advice to specific legal problems in this forum; rather one address legal and procedural issues generally.
Always be aware of deadlines for filing responses and respond to each - as I'm sure you know, failure to file response timely has serious consequences. You have 30 days to respond to the 425.16 special motion to strike.
The suspension of discovery on filing of the 425.16 special motion to strike provided for by CCCP425.16(g) does not apply in the context of other court filings.
Court filings become public record as soon as they're filed with the Clerk of Court, so there is no issue of such answers to motions being 'discoverable': perforce they become matters of public record.
Also, under CCP425.16(c), whoever prevails on the special motion to strike can recover reasonable legal fees.
