"The amounts a party received from The Histadrut to fund the election campaign of The Histadrut... will not be considered as a contribution... as long as the party didn't exceed article 7(d)". Article 7d states the expenditures ceiling for on-going activities allowed to a party.

Basically, parties can recieve donations only from Israeli individuals. However, the General Labor Organization (The Histadrut) may give money to parties in order to help them finance their Hisdadrot election campaign , and, as long as the party doesn't exceed its expenditures ceiling for on-going (regular, not in relation to campaing) activities, it is not considered as a donation at all.
