(2) he acts in reasonable reliance upon an official statement of the law, afterward determined to be invalid or erroneous, contained in:
(A) a statute;
(B) an opinion or order of court; or
(C) an official interpretation of the statute, rule, or order defining the offenses made by a public official or agency legally authorized to interpret that statute, rule, or order.
(c) The burden of injecting the issue of reasonable belief that conduct does not constitute an offense under paragraph (b) (1) and (2) is on the defendant.History: 1979, PL 16-43 § 2.
