In GB, the importance of phrase-structure rules has dwindled in favour of nearness conditions. Today, nearness conditions play a major role in defining the correct linguis- tic representations. They are expressed in terms of special binary relations on trees called command relations. Yet, while the formal theory of phrase-structure gram- mars is quite advanced, no formal investi- gation into the properties of command re- lations has been done. We will try to close this gap. In particular, we will study the in- trinsic properties of command relations as relations on trees as well as the possibil- ity to reduce nearness conditions expressed by command relations to phrase-structure rules.
