You must have a strong theoretical reason in order to justify, why some error terms should be correlated. For example, you may argue that error terms should be correlated because the underlying variables are under influence of a factor different from the latent dimension supposed to be measured, such as social desirability or some other response bias. In the article, you must explain the reason for error correlation.
