Lebron-Guzman v. HHS ( 1999 )

[NOT FOR PUBLICATION NOT TO BE CITED AS PRECEDENT] United States Court of Appeals For the First Circuit No. 99-1410 MARCOS A. LEBRON-GUZMAN, Plaintiff, Appellant, v. HHS, Defendant, Appellee. APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF PUERTO RICO [Hon. Jaime Pieras, Jr., U.S. District Judge] Before Torruella, Chief Judge, Stahl and Lipez, Circuit Judges. Salvador Medina De La Cruz on brief for appellant. Guillermo Gil, United States Attorney, Lilliam Mendoza Toro, Assistant U.S. Attorney, and Robert J. Triba, Chief Counsel, Social Security Administration, on brief for appellee. December 3, 1999 Per Curiam. Having reviewed the record with care, we find that substantial evidence supports the ALJ's decision that claimant did not show that prior to the expiration of his insured status he had a medically determinable impairment or combination of impairments which precluded the performance of his past relevant work. We apprehend no error in the ALJ's evaluation of conflicting medical opinions about the claimant's residual functional capacity, see 20 C.F.R. 404.1527(e)(2), (f), nor in the determination that claimant had not produced credible proof of the onset of a severe mental impairment prior to the expiration of his insured status. See 20 C.F.R. 404.131(b). Affirmed. See Loc. R. 27(c).
