Supreme Court quashes social security court ruling for failing to conduct evidence proceedings on repatriant status under citizenship law.

The Supreme Court quashed the appellate court's decision denying the applicant's pension claim due to an alleged failure to recognize her as a repatriant. The applicant argued she was a Polish national by birth or descent who moved to Poland with a residence permit, while the lower court incorrectly applied citizenship acquisition rules based solely on marriage. The Supreme Court ruled that the lower court lacked authority to make arbitrary factual determinations without evidence and must conduct proceedings to verify the specific circumstances of her arrival and intent to settle permanently.
