body: <p>According to the <a href="https://hyperledger.github.io/composer/latest/reference/acl_language" rel="nofollow noreferrer">hyperledger ACL documentation</a> and <a href="https://hyperledger.github.io/composer/latest/tutorials/acl-trading" rel="nofollow noreferrer">ACL trading tutorial</a>, ACL's can be used to add user access restrictions to certain assets and transactions within a hyperledger composer business network. </p>
  
  <p>Can ACL's be implemented to restrict participant access to certain queries as well ? </p>
