N2  - Quantitative estimates are provided for the influence of luminosity selection effects present in a bright source sample on the observed correlation of the depolarisation rate &#923; &half; with redshift z . It is shown that the observed correlation is partly intrinsic and partly due to luminosity effects. More specifically, we find that &#126;46% of the observed &#923; &half; correlation with z can be attributed to strong luminosity selection effects in the sample. This shows that a significant fraction (&#126;54%) of the observed correlation is cosmological in origin. It is concluded that there is a cosmological evolution of &#923; &half;, over and above that resulting from luminosity selection effects, which may be related to the epoch dependent properties of the ambient medium through which the radio source components propagate.
