To the extent that this Basic Law confers on the Federation the power to legislate, the Federation may grant cantons financial assistance for particularly important investments by cantons, municipalities, or associations of municipalities which are necessary to:
avert a disturbance of the overall economic equilibrium,
Level differing economic capacities,
promote economic growth, or
support projects involving municipalities from different cantons
The Federation may grant financial assistance even outside its field of legislative powers in cases of natural disasters or exceptional emergency situations beyond governmental control and substantially harmful to the canton’s financial capacity.
