As a consequence, we conclude that models which treat vector meson exchange contributions to the weak conversion process $ΛN\rightarrow NN$ assuming such weak couplings to satisfy the $ΔI=1/2$ rule are unlikely to be reliable.13 pages, uses REVTEX Entire manuscript available as a ps file at http://www.physics.adelaide.edu.au/theory/home.html .
