Translation:Arukh ha-Shulchan…
“ Section 1 Even though an individual cannot act as judge and litigants cannot rule for themselves, there are times when one may decide the application of the law for oneself. For example, if one should see his object in the hand of another, and it is clear that the other's intention is to steal it, damage it or otherwise refuse to return it, he can grab it away and does not have to hold himself back until he can file a complaint with the court. ”
