Equality and the courts

I keep thinking about equality. One thing I know for sure is that there is no equality in the courts. If each party to a litigation has a lawyer then the process might be defined as being equal. But what about those that do not have a lawyer. How could that even remotely be considered equal. I am advocating that no one should be allowed in a higher court like the supreme court or appeal court unless they are represented by a lawyer. Then equality will be a bit more equal.
