The Buzaglo test is a phrase coined in Israeli law which subsequently developed into an idiom in Israel.
Yadlin, an important figure in the dominant Mapai party who was under consideration for the position of governor of the Bank of Israel, was suspected of theft and receiving bribes.
Yadlin asked to be questioned by the police in his office, but Barak refused on the grounds that the law should treat all equally, without regards to their social standing.
Yadlin was questioned in a police facility, and was later convicted and sentenced to five years' imprisonment.
Barak's decision was significant at the time due to the prolonged dominance of the Mapai party in Israeli politics and society.
