planned expenditure for the coming years, the accumulations in the state special budget would be used up already in a couple of years. 3.2. The principle of protection of legitimate expectations following from Article 1 of the Constitution does not restrict the legislator’s rights to deviate from the previous practice, even if it has been stable. Such a deviation is not only acceptable but also necessary in the cases when a more suitable and obviously more appropriate solution has to be chosen. Although the principle of protection of legitimate expectations has constitutional value, protection of other persons' rights and social welfare has an equal constitutional value, and it can be provided by efficient redistribution of common wealth and balancing revenue and expenditure of the state. The principle of protection of legitimate expectations does not mean that the laws cannot be changed.

Paragraph One of Article 3 of the Disbursement Law complies with Article 91 of the Constitution, since the purpose of social security benefits is to guarantee means for living to persons when they cannot be actively involved in employment legal relationships due to various reasons and thus to provide means for living by themselves. Old age is one of the cases when a person receives social security benefits – old-age pension. The differentiated amount of reduction in old-age pension for employed pensioners compared to non- employed pensioners and pensioners with other income is substantiated because employed pensioners have revenues from employment alongside with the state old-age pension and can provide means for living for themselves. Different treatment of persons subject to the enactment contained in Paragraph One of Article 3 of the Disbursement Law is proportionate to the benefit for the society. The impugned provision helps to guarantee disbursements of social insurance services, and the established restrictions of rights are balanced taking into account the age of a person as a social risk that affects the ability of the person to provide means of living for himself or herself. Whereas employed pensioners and able-bodied persons in active employment are not in an equal and comparable situation in accordance with Paragraph One of 9
