This is a black lung case. The district court remanded it to the Secretary on the ground he had employed an incorrect legal standard. That decision must be reversed under our decision in Ingram v. Califano, 547 F.2d 904 (CA5, 1977).

Issues raised on this appeal other than the Ingram ruling that disability must be proved to have existed before July 1, 1973, should be addressed to the district court.

REVERSED and REMANDED.

ON PETITION FOR REHEARING

PER CURIAM:

In our opinion of April 27, 1977, this court stated that at the district court level upon remand the appellee May was fr.ee to raise any issues, other than the ingram v. Califano, 547 F.2d 904 (CA5, 1977), ruling that disability must be proved to have existed before July 1, 1973. As the government correctly points out, this includes whether the administrative law judge gave proper consideration to post-July 1, 1973, evidence as it relates back to any possible pre-existing condition.

The petition for rehearing is DENIED.
