KYA (joint ministerial decision)
A decision signed jointly by two or more ministers. It often sets amounts, conditions or procedures for a benefit or obligation.
A KYA is a decision signed jointly by several ministers and published in the FEK. It often sets the amounts and conditions of a benefit.
When a KYA changes, the rule behind a calculator changes too. That is why each tool shows its source and the date it was checked.
