(KTRS) – In November Missouri voters approved limits on campaign contributions.

Next week a judge could temporarily stop the caps from taking effect. A business group filed a lawsuit, saying the constitutional amendment unfairly keeps them from making some donations.

The new rules cap contributions to individual candidates at $2,600 an election and donations to a political part at $25,000 per election cycle. The judge is expected to hear arguments in the case on December 29.
