I've only had District Judges. I had the tip to request one from the outset. After that, it always said - referred to a DJ because case was heard previously by a DJ. The feedback I've had, heard and seen about magistrates is - you get woolly outcomes. They don't seem to have the authority and, frankly, legal experience or knowledge, to make the kind of forthright no nonsense decisions and cut through the crap - as Km5 says.
Personally I don't think family cases should be heard by Magistrates - it's ridiculous - these are childrens lives and delay is the enemy. I think they get some training, but they are not lawyers and the very fact we have to go to court to ask to see our children is bad enough, but to have to have three old fogeys sit there deliberating our destiny is even worse. At least with a DJ - they know the law inside out - and when there are no welfare issues - there is no reason for a Father not to have a good order - and they know that.
Having said that, some people have had good outcomes with magistrates and a Dad whose partner got tips on here, recently got a 50/50 order with magistrates. So it depends. Also there are some woolly Judges who don't give two hoots either. There are also some truly excellent Judges who really care and take no nonsense.
The way the system works is also strange. Even with a very good Judge, if the ex's solicitor raises a welfare issue and wants further investigation, they sometimes just grant that - because they err on the side of caution with safety and kids. Which is why the system can be so easily manipulated by an ex and her solicitor! But - if you also had a lawyer who argued against that, the Judge can be persuaded, on a point of law and by sound argument - that further investigation is not necessary - and make their own decisions. They have the training, and therefore the confidence to actually "judge".
I completely see your point - young child, three magistrates, possibly women - society view about Mothers - that you fear it might be a bit blinkered or biased. All I can say is - do your best to put your arguments forwards and come across well. Impress them. Do a good position statement - that helps the magistrates get to grips with what is going on - have it full of blindingly reasonable and logical points and they will agree and warm to that.
I'm a big fan of position statements - swaying opinion from the outset on paper.
Don't always believe what solicitors say either. However, there is a shortage of DJ's since the pandemic. Usually if a case has some complexities then asking for a DJ is accepted. It depends on how your case is and what the issues are. But I think if I had been waiting 1.5 years and not had a final hearing, I'd be asking for a District Judge too.
Yes it probably would adjourn a hearing date if the request was accepted, which would cause some delay. When is your next hearing date? And why has it taken 1.5 years? I assume because your child was very young initially and you've had to keep going back to increase time?
I think you need someone to be quite robust now - if no agreement then it should go to a final hearing.
