International standards generally give the following indications in this area: donations from foreign states or enterprises may be banned but this prohibition should not prevent financial donations from nationals living abroad. In order to establish whether the prohibition of financing from abroad is problematic (disproportionate) in light of Article 11 of the ECHR, every individual case has to be considered separately in the context of the general legislation on financing of parties. While international standards tend to be restrictive when it comes to foreign funding of political parties and electoral campaigns, they generally refer to the situation of foreign donors, in the interests of avoiding undue influence of foreign interests in domestic political affairs.
