  We consider pair production of LSP staus at the LHC within R-parity violating
supersymmetry. The staus decay into Standard Model leptons through the LL\=E
operator. Using CheckMATE we have recast multileptonic searches to test such
scenarios. We show for the first time that using these analyses the stau mass
can be constrained up to 345 GeV, depending on the stau decay mode, as well as
the stau mixing angle. However, there is for all scenarios a significant gap
between the lower LEP limit on the stau mass and the onset of the LHC
sensitivity. This approach can be used in the future to constrain the stau
sector in the context of RPV lepton-number violating models.
