Key legal question
Whether the cantonal court arbitrarily assessed the wife's hypothetical income from full-time cleaning work.
Extracted holding
No. The wife failed to show that the finding was untenable; her objections were largely appellatory and did not disprove the feasibility of full-time work or the income level used.
Extracted reasoning
For constitutional review of maintenance decisions, the Court examines only clearly substantiated constitutional claims. The wife conceded the increase of earning capacity was in principle reasonable, and her assertions did not demonstrate that full-time work was impossible. Her limited job-search efforts further supported the cantonal finding.
