of theoretical assumptions. Proving SUSY will require not only to discover new particles and measure their masses, decay widths and production cross sections, but also\
  $\bullet$ verify that they are superpartners, [*i.e.*]{} measure their spin and parity, gauge quantum numbers and couplings,\
  $\bullet$ reconstruct the low-energy SUSY breaking parameters without assuming a specific scenario,\
  $\bullet$ and ultimately unravel the SUSY breaking mechanism sheding light on physics at high (GUT?, Planck?) scale.\
Since the last International Linear Collider Workshop in Paris (LCWS04) members of the SUSY working groups were very active delivering many talks during three regional meetings: the ALCPG Workshop in Victoria, the ECFA Workshop in Durham, and the ACFA Workshop in Taipei; the transparencies can be found in [@meetings]. Here in Stanford (LCWS05) we had 21 presentations in the SUSY WG session alone, and a number of SUSY related talks in other sessions. It is impossible to give justice to all in my talk (and these proceedings) and I apologize for omissions.

ACTIVITIES
==========

The aim of our activities is to strengthen the physics case for the $e^+e^-$ ILC demonstrating that it would be an indispensable tool. Our activities also include studies of synergy of the LHC and the
