Social security contribution dispute dismissed; no appeal allowed for determining contribution base amount under Polish law.

The Supreme Court dismissed the cassation appeal filed by a business owner against a social security fund decision regarding contribution amounts. The core dispute concerned whether the contribution base for employees working abroad should be the declared wage or a specific statutory minimum, rather than a calculation error. Since the case involved determining the legal basis for calculating contributions, the court ruled that cassation proceedings were procedurally inadmissible under the relevant code.
