Question juridique clé
Whether the cantonal court arbitrarily assessed the evidence by finding E.'s work capacity reduced by 80% until 11 June 1997.
Solution extraite
No arbitrariness was shown; the cantonal court could infer a very substantial but not total incapacity from the medical and testimonial evidence.
Motifs extraits
The Federal Court held that the precise percentage did not directly follow from any single item of evidence, but the cantonal judges were entitled to evaluate the whole record. Given the serious injury to the right arm, the plaster and sling, and E.'s duties in a small technical company including mounting work and heavy handling, the finding of an 80% incapacity was not manifestly untenable.
