A massive brawl broke out between the ruling Justice and Development Party (AKP) and the Peoples' Democratic Party (HDP) during a Turkish parliament meeting recently. According to Russia Today, the fight started as the two sides debated a constitutional amendment that would strip lawmakers of their legal immunity.
Tensions were already high as Turkish president Erdogan has been accusing HDP of ties to the outlawed Kurdistan Workers' Party (PKK), and the constitutional amendment that was being debated was allegedly worrying members of the HDP that they'd potentially be open to prosecution for any opposition of the ruling party.

After all of the mayhem, the parliament did end up actually approving the bill, according to Reuters.
This is presumably not going on the best practices list in any civics textbooks.
