Supreme Court allows supplementary grounds claim and spousal support change based on changed circumstances.

The Supreme Court permitted the introduction of supplementary grounds to the appeal and granted a modification of spousal support due to altered conditions. The appellant argued that new facts justified a change in the support amount, while the respondent contested the relevance of these post-filing developments. The court ruled that procedural rules allow supplementary arguments before legislative changes and that material changes in the family situation warrant an adjustment of the support obligation.
