Appeal from the United States Court of Appeals for Veterans Claims in 05-816, Judge
Lawrence B. Hagel.



                            DECIDED: May 21, 2008



Before NEWMAN, Circuit Judge, PLAGER, Senior Circuit Judge, and SCHALL, Circuit
Judge.

SCHALL, Circuit Judge.

                                      DECISION

      Earl M. Rauch appeals the final decision of the United States Court of Appeals

for Veterans Claims (“Veterans Court”) that affirmed the December 14, 2004 decision of

the Board of Veterans’ Appeals (“Board”) denying Mr. Rauch’s claim to service

connection for respiratory disease. Rauch v. Nicholson, No. 05-816, 

(Vet. App. Feb. 22, 2007). We dismiss for lack of jurisdiction.
                                      DISCUSSION

                                            I.

       The relevant facts are set forth in the decisions of the Board and Veterans Court.

Briefly, Mr. Rauch served on active duty in the United States Army from November of

1971 to April of 1972, and from November of 1990 to May of 1991. In December of

1997, Mr. Rauch filed a claim with the Department of Veterans Affairs (“VA”) seeking

service connection for chronic obstructive pulmonary disease allegedly caused by

exposure to toxins during the First Gulf War. In October of 1998, a VA regional office

(“RO”) denied service connection for chronic obstructive pulmonary disease on the

ground that the diagnosis was too far removed from service. Mr. Rauch appealed the

decision, and in October of 2002, the Board remanded the case to the RO for further

development. Eventually, the RO again denied service connection. It did so largely on

the basis of the opinion of Dr. C. Paul Loehnen, a private physician to whom the RO

had referred Mr. Rauch’s case. Dr. Loehnen opined that Mr. Rauch’s “difficulties” were

“in large part secondary to his morbid obesity” and commented that he did not find

“anything in the record that would lead [him] to conclude [that] there is a service-related

disability regarding [Mr. Rauch’s] pulmonary status.”

       Mr. Rauch again appealed to the Board, which this time denied his claim.

Reviewing the evidence before it, the Board credited the opinion of Dr. Loehnen over

that of another doctor who had examined Mr. Rauch.            The Board noted that Dr.

Loehnen had explained that exposure to toxins would typically lead to acute problems

during service and that Mr. Rauch’s records reflected no lung problems during his time

in service.




2007-7199                                   2
      Following the Board’s decision, Mr. Rauch appealed to the Veterans Court. As

noted above, the court affirmed the Board’s denial of Mr. Rauch’s claim. In its decision

the court rejected the two contentions raised by Mr. Rauch on appeal.           The first

contention was that the VA’s further development of the claim (asking Dr. Loehnen for

an opinion) was improper in view of the fact that a 1998 VA medical examination by Dr.

Rick A. Lamb reflected a diagnosis of chronic obstructive pulmonary disease and noted

that Mr. Rauch had been “in an area of Saudi Arabia that was dense with oil smoke

after oil fires were lit in Kuwait.” According to Mr. Rauch, under these circumstances,

the further development of the claim was improper because it was for the purpose of

obtaining evidence to deny the claim. Mr. Rauch’s second contention was that RO

personnel “were biased against [his] claim in violation of due process of law.” In Mr.

Rauch’s view, this was evidenced by the fact that information that tended to detract from

a finding of service connection was presented to Dr. Loehnen and that communications

at the RO unduly “suggest[ed] an answer or limit[ed] the field of inquiry by the expert”

(Dr. Loehnen).   The Veterans Court rejected both contentions. As far as the issue of

further development of Mr. Rauch’s claim was concerned, the court determined, the VA

had discretion to develop additional evidence because of the conflicting and unclear

nature of the evidence before the VA on the issue of service connection. Addressing

Mr. Rauch’s claim of bias, the court stated that it did not agree that the RO documents

presented to Dr. Loehnen suggested a predetermined answer with respect to Mr.

Rauch’s claim. In addition, the court noted that Mr. Rauch did not challenge the

accuracy of the information that was given to Dr. Loehnen. The court also noted that




2007-7199                                  3
the questions which were posed to Dr. Loehnen were asked in an unbiased fashion.

Following the Veterans Court’s decision, Mr. Rauch timely appealed to this court.

                                            II.

      Our authority to review decisions of the Veterans Court is governed by statute.

Pursuant to 38 U.S.C. § 7292(c), we have “exclusive jurisdiction to review and decide

any challenge to the validity of any statute or regulation or any interpretation thereof

brought under [that] section, and to interpret constitutional and statutory provisions, to

the extent presented and necessary to a decision.” However, “[e]xcept to the extent

that an appeal under . . . chapter [72] presents a constitutional issue, [we] may not

review (A) a challenge to a factual determination, or (B) a challenge to a law or

regulation as applied to the facts of a particular case.” 38 U.S.C. § 7292(d)(2)(2000).

      On appeal, as he did before the Veterans Court, Mr. Rauch contends that

personnel at the RO were biased against his claim. He argues that we have jurisdiction

over his appeal because, by making this argument, he is asserting a free-standing

constitutional claim based upon a violation of due process. See In re Bailey, 

, 865 (Fed. Cir. 1999) (establishing this court’s jurisdiction over free-standing

constitutional issues in appeals from the Veterans Court). While it is true that we have

held that we have jurisdiction over free-standing constitutional claims, see 

has not asserted such a claim. Rather, in the face of factual determinations that

he does not challenge and that demonstrate the absence of impropriety on the part of

the individuals involved, Mr. Rauch simply makes bald, unsupported assertions of bias

on the part of the RO. Such assertions are insufficient to make out a true constitutional

claim. Thus, Mr. Rauch has not presented a claim within our jurisdiction.

       For the foregoing reasons, we must dismiss Mr. Rauch’s appeal for lack of

jurisdiction.

       No costs.
