( CNN ) -- Thousands took to the streets of Madrid Saturday to protest against a proposed law that would , among other things , impose stiff fines on illegal demonstrations , according to state-run broadcaster TVE . Much of the protest was peaceful , but a small group clashed with riot police and seven people were arrested . Officials said at least 23 people were injured , including 14 police officers . `` The voice of the people is not illegal , '' protesters shouted as they were met by 1,250 riot police , TVE reported . Under the proposed law , unauthorized demonstrations in front of the Parliament building carry a fine of up to 30,000 euros ( about $ 41,000 ) , but the measure is likely to pass as conservatives hold the majority in the government . Spain has seen its share of protests since the government imposed austerity measures to comply with European Union demands . Spain 's unemployment is at 26 % , one of the highest jobless rates in Europe .
