But at least the lawyers have legal training, qualifications, and insurance. Also MFs can't charge for conducting litigation (which they are prevented from doing anyway)
To quote from a summary of what Nick Wall in the court of appeal said recently on the subject:
"That left the question of the McKenzie friend. It would appear that the judge had not been happy with the representative. Although the judge found that there was a possibility that the mother had been intimidated by the father's McKenzie friend, the Court of Appeal found that that was a difficult finding to sustain as the McKenzie friend had not actually cross-examined the mother. However, it would appear that the judge also felt that the McKenzie friend may have overstepped the mark by preparing a document on the father's behalf which referred to the name of a child who was nothing to do with the proceedings. Although the father conceded that the McKenzie friend had done 20 per cent of the work, he did point out that he had himself done the remaining 80 per cent.
The Court of Appeal reminded all parties what McKenzie friends may not do, as laid down by the guidance at (2010) 2 F.L.R. 962:
"MFs may not i) act as the litigants' agent in relation to the proceedings; ii) manage litigants' cases outside court, for example by signing court documents; or iii) address the court, make oral submissions or examine witnesses."
In this case, the appellate court supported the view of the managing judge that the McKenzie friend had wrongly stepped "into the realms of conducting litigation". The managing judge had said that even if the McKenzie friend had done 20 per cent of the work, "it was 20 per cent too much". She had no objection to the father appointing another McKenzie friend. As far as the appellate court was concerned there did seem to be adequate reasons for the judge to have acted as she did. She had also read the curriculum vitae of the McKenzie friend and referred to the guidance laid down by the court. This was not a case management decision which the court would interfere with, notwithstanding their view that it was reached "in a swift and it must be said somewhat rough and ready way".
