Poland's Supreme Court has ruled against a businessman who refused to print posters for an LGBT business group because he did not want to "promote" the gay rights movement.

The country's top court said it was upholding the ruling of a lower court. The Regional Court in Lodz had argued that the principle of equality before the law meant the businessman did not have the right to withhold services from the LGBT Business Forum.

The case was brought to the Supreme Court by Zbigniew Ziobro, the justice minister and attorney general. He called Thursday's ruling "wrong" and a "violation of the constitutional principle of freedom of conscience."

The Campaign Against Homophobia, which gave legal support to the LGBT Business Forum, welcomed the ruling.
