We critically reexamine the prospects for the observation of the \ensuremathΔL=2 lepton-number-violating process e^\ensuremath-e^\ensuremath-\ensuremath→W^\ensuremath-W^\ensuremath- using the e^\ensuremath-e^\ensuremath- option of a high-energy e+e^\ensuremath- collider (NLC). We find that, except in the most contrived scenarios, constraints from neutrinoless double \ensuremathβ decay render the process unobservable at an NLC of √(s)<2 TeV. Other \ensuremathΔL=2 processes such as \ensuremathγ\ensuremathγ\ensuremath→\ensuremathℓ+\ensuremathℓ+W^\ensuremath-W^\ensuremath-, e^\ensuremath-\ensuremathγ\ensuremath→\ensuremathνe\ensuremathℓ^\ensuremath-\ensuremathℓ^\ensuremath-W+, e^\ensuremath-e^\ensuremath-\ensuremath→\ensuremathνe\ensuremathνe\ensuremathℓ^\ensuremath-\ensuremathℓ^\ensuremath-(\ensuremathℓ=\ensuremathμ, \ensuremathτ), and e^\ensuremath-\ensuremathγ\ensuremath→e+W^\ensuremath-W^\ensuremath-, which use various options of the NLC, require a √(s) of at least 4 TeV for observability.
