Cooperative members' surplus share rights depend on work contribution regardless of specific distribution method.

The Supreme Court ruled that cooperative members are entitled to a proportional share of the surplus based on their work contribution, even when distributed via interest or capital increases. The lower courts had initially invalidated internal rules restricting distribution to full-year employees, ordering proportional payments for partial-year members. The Court affirmed that all surplus distribution methods listed in the query constitute remuneration for work and must adhere to the statutory principle of proportionality to work input.
