2.  The  Rules  govern  all  proceedings  after  their  effective 
date  except  to  the  extent  that,  in  the  opinion  of  the  Court, 
their  application  to  a  pending  matter  would  not  be  feasible 
or would work an injustice, in which event the former proce­
dure applies.

its  brief  on  the  merits  prior  to  the  effective  date  of  these 
revised  Rules,  all  remaining  briefs  in  that  case  may  comply 
with  the  October  1,  2007,  version  of  the  Rules  of  the  Su­
preme  Court  of  the  United  States  rather  than  with  these 
revised Rules.
