SAN FRANCISCO — For months, internal campaign documents from Proposition 8 backers were subjected to discovery battles and magistrate time, but they remained hidden from public view.

That changed Wednesday. Lawyers representing same-sex couples persuaded Chief Judge Vaughn Walker to allow a handful of those documents into the record, over repeated objections from Yes on 8 General Counsel Andrew Pugno. The e-mails and other memos detail the Church of Latter Day Saints’ involvement in Proposition 8 — for instance, that there was at least one LDS volunteer working in every California ZIP code.
