1
This is a petition for review of a final order of deportation under the then applicable section 106(a) of the Immigration and Nationality Act, 8 U.S.C. § 1105a(a) (1995). The specific issue is whether substantial evidence supports the Board of Immigration Appeals' adverse finding of credibility, leading it to dismiss petitioner's appeal from an Immigration Judge's decision denying his request for asylum.


2
Petitioner, a 26-year-old citizen of El Salvador, was placed in deportation proceedings in May 1992, after entering the United States without inspection. He subsequently filed an application for asylum, claiming that he and a brother had witnessed the kidnaping of his uncle and father, the latter being a known supporter of the government's military establishment, by guerillas who later killed both men. He feared the same fate if he were to return to El Salvador.


3
The Board of Immigration Appeals, after reopening an Immigration Judge's in absentia order of deportation for lack of clear notice of hearing, and after rejecting the Immigration Judge's adverse finding of credibility for lack of "specific and cogent reasons," made its own de novo adverse finding of credibility. It found discrepancies in the testimony and exhibits in the record that "are significant and go directly to the heart of [the] asylum claim." The Board acknowledged that such a kidnaping was consistent with conditions in El Salvador in January 1992, but added:


4
However, what cannot be explained by general country conditions is why the respondent alternatively stated that he had only witnessed his father's kidnaping, but not his uncle's, or that he witnessed both men being kidnaped; that after the uniformed men sent him away, that he never saw his father again, or that his father and his uncle were both paraded past his house; that his father had told him where they were going, or that he had not told him; and, most importantly, why his mother's letter conflicts with any of the versions of the story recounted by the respondent.


5
After reviewing all of the testimony and documents in the record, we affirm.


6
The petitioner in a case such as this faces a heavy burden. To be eligible for asylum, he must establish through credible and specific evidence in the record that his fear of persecution is both genuine and objectively reasonable. See Aguilar-Solis v. INS, 168 F.3d 565, 569-73 (lst Cir. 1999). The BIA's determination that the petitioner has failed to prove his case may be reversed only if the record, viewed in its entirety, would compel a contrary conclusion. See id. at 569. We add that an adverse credibility determination cannot rest on trivia but must be based on discrepancies that "`involved the heart of the asylum claim,'" De Leon-Barrios v. INS, 116 F.3d 391, 393-94 (9th Cir. 1997) (citation omitted).


7
Petitioner criticizes the Board for overlooking "the true story presented" of the murders -- a child's witnessing his father's abduction, and a grief- and terror-stricken family -- and, instead, focusing "its attention on minor, relatively inconsequential details, . . . violat[ing] its responsibility to review the record as a whole, with an eye to the cultural, linguistic, and emotional hurdles unique to asylum applicants."


8
To test the substantiality of the inconsistencies, we, like the Board, consider the description of the underlying basis of petitioner's fear in (1) his asylum application, dated July 5, 1994; (2) his declaration, filed with the application; (3) a letter from petitioner's mother to his counsel, dated August 12, 1994 (which, contrary to petitioner's argument, was explicitly made part of the record), and (4) petitioner's testimony at a hearing on February 10, 1995. We divide the various statements into three headings: location of the abduction; details of the abduction; and subsequent viewing of the victims. We consider the statements in the order in which they were made.


9
Location. In his application, petitioner stated that he and his brother were working in a field when his father and uncle were abducted. In his testimony, however, he denied ever having said that. In the declaration, filed with the application, petitioner stated that, after working on house repairs, he and his brother were going to a field to get animals when the abduction took place. Petitioner's mother, in her letter, said simply that her husband was taken from a peace meeting, without anyone noticing. In petitioner's testimony, some six months later, he said that he and his brother were going with their father to an unknown destination. Indeed, he said that this was the only time they had ever gone with their father when he did not tell them where they were going.


10
Abduction. In petitioner's application, he stated that three men dressed in what looked like army uniforms abducted both his father and uncle while he and his brother watched. In his declaration, filed at the same time, he stated that three men in green uniforms with helmets took away his father. He did not mention seeing his uncle. Petitioner's mother, in her letter, made no mention of the uncle. In his testimony, petitioner said that two men in uniform took his father. He said he did not see his uncle. He learned of his uncle's fate only when a son of his uncle later told him.


11
Subsequent viewing. In petitioner's application, he stated that, some time after the initial abduction, he saw his father and uncle, their hands tied behind their backs, being taken by his house. The same observation was reported in his declaration. The mother's letter made no mention of this viewing. Finally, in his testimony, petitioner denied having made such a statement and said that, after the abduction, he never saw his father again. He stated, however, that his father was taken past his house, without indicating how he knew this.


12
Petitioner vigorously argues that these various versions were merely attempts to clarify, and that in fact they should enhance, not diminish, his credibility, because they simplified rather than embellished his case. Perhaps petitioner so intended, but the problem of inconsistencies remains. His argument that his mother's peace meeting version of the abduction merely indicates her superior knowledge of where his father intended to go offers no explanation why she made no mention of her sons' traumatic report of the abduction. Similarly, petitioner's argument that his father had made an early statement about going to pick up animals but that at the time of the abduction they were going "another way" without any gear to use with animals cannot be reconciled with his declaration that at the time of the abduction they were going to a field to get animals. These are not explanations; they are non sequiturs.


13
What can we make of all this? We confess our inability at this juncture to penetrate to the absolute truth of what happened on that day of alleged abduction in January 1992. It may be questioned why, in a guerilla-dominated area, guerillas would dress in government clothing to seize a pro-government sympathizer. It may also be questioned how a brother of petitioner could continue to live, apparently safely, in El Salvador. Leaving such queries aside, we acknowledge that petitioner's basic story could be true.


14
But can we say that the inconsistencies outlined above are at most marginal, mere gossamer threads? Or that they must all be attributed to difficulties of language or understanding? Or can we say, as the dissenting Board member thought, that the Board's emphasizing the significance of differing versions of a traumatic event was "unsupported conjecture"?


15
Unlike the cases cited to us by petitioner, such as Canjura-Flores v. INS, 784 F.2d 885, 889 (9th Cir. 1985), and Damaize-Job v. INS, 787 F.2d 1332, 1337 (9th Cir. 1986), the inconsistencies noted by the Board were more than several and more than minor, such as an error in dates or a typographical error. Petitioner calls our attention to Cordero-Trejo v. INS, 40 F.3d 482 (lst Cir. 1994), in which we held that the Board's negative credibility findings were without record foundation. That case is helpful because it presents a Board decision that we felt comfortable in setting aside. Its credibility finding was based on one alleged inconsistency that we deemed ephemeral (i.e., a supposed inconsistency between calling attackers "unknown armed men" and "death squads, id. at 488); a hypertechnical challenge to the authenticity of documents; and eight "implausibilit[ies]," id. at 490.


16
Here, in contrast, the multiple inconsistencies went to the central facts of the triggering event. The discrepancies concerned the where, the who, the when and the what of the abduction. And the only alleged "implausibility" is the Board's observation that if petitioner had in fact been present at such a traumatic event as a kidnaping of his father, he would not likely have overlooked the major details of that event. But this is the very stuff of legitimate impeachment.


17
Moreover, not only were there multiple differences, but they were not greatly separated in time. The application and declaration, prepared with the assistance of counsel, were dated the same day; the mother's letter came a month later; and the testimony followed six months later. Petitioner stated that all written statements had been read to him. There was no attempt, although there was ample time, to elaborate upon or explain the mother's varying interpretation.


18
In short, we know of no principled basis for reversing the Board's decision short of saying that an appellate court can conduct de novo review of every non-frivolous case involving non-English speaking parties. This we cannot do. The Board's finding of adverse credibility was supported by substantial evidence, which it succinctly summarized. Its decision to allow timely voluntary departure, or, failing that, to order deportation must be


19
Affirmed.
