A, a government employee, was administratively charged with immorality for having an affair with B, a co-employee in the same office who believed him to be single. To exculpate himself, A testified that he was single and was willing to marry B. He induced C to testify and C did testify that B was single. The truth, however, was that A had earlier married D, now a neighbor of C. Is A guilty of perjury? Are A and C guilty of subornation of perjury? (1997 BAR)
