Key legal question
Whether the cantonal court arbitrarily assessed the evidence on the wife's earning capacity and income.
Extracted holding
No. The cantonal court could rely on the contradictions between the medical certificate, salary slip, bank statement, and witness testimony; its credibility assessment was not manifestly untenable.
Extracted reasoning
The documentary evidence conflicted internally and with the testimony, and the salary amounts did not appear on the bank statement. The witness was not shown to be incapable of testifying or implausible merely because of family tensions.
