(Back in the good old days – there were no DMV hearings to deal with, and the court handled any license suspension meted out in a case).

De Yoe's San Diego DMV hearing victories from over the years have been truly stupendous.

Success in Negotiating Alternative Sentencing

Another area where Attorney De Yoe has been victorious for his clients over the years concerns alternative sentencing in tough DUI cases, where prior offenses cause one to face huge jail or prison terms. Mark R. De Yoe, APLC has worked very hard in getting clients what is known as house arrest, with an electronic ankle bracelet, for many years.

In a very recent case, Mark obtained house arrest, electronic surveillance with a SCRAM bracelet in very tough, high blood-alcohol felony DUI case.

Mark has also obtained alternative sentencing in a wide variety of situations for those facing very tough third time DUI sentencing.
