Sent 4: The full report can be viewed at (www.calbar.org).
Sent 5: In her year-long odyssey through the California justice system, Katherine, a 35-year-old single mother with three children, experienced failure at every turn.
Sent 6: Leaving her abusive husband, she moved into the only apartment she could afford, and soon discovered a broken toilet and non- working oven, rats and roaches, and a fourthfloor landing with no railing.
Sent 7: She began withholding rent pending repairs her landlord refused to make, but then her Medi-Cal benefits were cut off when she could not provide rent receipts.
Sent 8: She lost health care for her children and herself, although she is a borderline diabetic in need of medication and her children were suffering from rat bites.
Sent 9: Katherine tried to seek help through the courts.
Sent 10: Representing herself at an administrative hearing, she lost her appeal to restore Medi-Cal benefits because she did not have proper documentation of the rent account.
Sent 11: When she went to a courthouse to file a complaint against her landlord, she found the process so confusing that she gave up and went home.
Sent 12: According to "The Path to Justice: A Five-Year Status Report on Access to Justice in California," prepared by the California Commission on Access to Justice, Katherine is just one of 4.6 million poor Californians whose basic civil legal needs -- often involving such critical needs as housing, health care, education, employment, safety and transportation -- are not being addressed.
Sent 13: California has a critical dearth of legal services for the poor, and, as this report makes clear, it is imperative that the state join with the federal government and private funders to increase resources so that all Californians, regardless of income, have equal access to our justice system.
Sent 14: Our justice system is predicated on the assumption that both parties will be represented by lawyers who act as gatekeepers and guides through a complex legal system that would otherwise be inaccessible to many of us.
Sent 15: Unfortunately, the most vulnerable members of our society are the least able to afford legal services.
Sent 16: California does have a strong network of legal aid organizations that try to help meet the needs of the poor, but there's just one legal aid lawyer available per 10,000 poor people.
Sent 17: We may promise "justice for all," but for those who can't afford a lawyer, that promise is often a lie.
Sent 18: In its new report, the Commission on Access to Justice notes some significant steps toward providing equal access to justice for all Californians.
Question: Why did Katherine represent herself and not seek legal services? (A) She could not afford an attorney and the legal system was too crowded to be a help to her (B) She was very smart (C) The most vulnerable members of our society are the least able to afford legal services (D) She could not afford her own lawyer, and there are not enough legal aid lawyers to help everyone in need (E) She could not afford it (F) She didn't want to pay it (G) She felt she had experienced her promblems and was best able to bring them to the attention of the court.

Sent 9: It was no subject of surprise that Brent had come back unexpectedly, for such was his usual custom.
