Scott Norris Johnson, a Carmichael attorney who has filed thousands of disability-access lawsuits across California, pleaded guilty Tuesday in Sacramento federal court to submitting a false tax return.

According to a plea agreement filed in the U.S. District Court for California’s Eastern District, Johnson reported total income in 2012 of $36,369 when bank deposits showed he received lawsuit settlement payments of more than $1.3 million. Such payments must be reported as income to the Internal Revenue Service.
